Some things to think about when reading through these two documents:
1. The basic purpose of Nixon's visit was to simply start a dialogue with the most populous nation in the world after decades of the US denying the existence of China and supporting Taiwan instead. Trump's visit had some similarities because the US and North Korea had no diplomatic relations for decades either. However, in the present case, Trump was visiting a pariah nation and there was growing concern about North Korea's nuclear weapons. Trump's goal to 'denuclearize' the Korean Peninsula.
2. In the current statement, the names of the two leaders are in the title. In the 1972 statement, they are not. Probably not a big deal, but still telling.
3. In both statements there are a lot of vague commitments with no actual specific steps or deadlines. In the Singapore statement, the most specific commitment is that North Korea "commits to work toward complete denuclearization of the Korean Peninsula." A further specific commitment is to return identified remains of POW's and MIA's.
The Shanghai agreement goes through many more issues including Vietnam (the US was still fighting there at the time), peace between India and China in Jammu and Kashmir, peace in Korea, and China and the US commit to a one China policy and the US will withdraw military bases from Taiwan. This was a huge concession on the part of Nixon radically changing US policy on China. There is also mention of cultural exchanges.
4. The Singapore statement includes a bit of self-aggrandizement when it mentions "a first, historic summit" and later, "Having acknowledged that the U.S.-DPRK summit — the first in history — was an epochal event of great significance in overcoming decades of tensions and hostilities between the two countries and for the opening up of a new future . . " (emphasis added) The Shanghai statement has no such language.
Nixon went to the most populous country in the world - opening relations that both saw as beneficial for trade and for peace in Asia and the world. Trump went to one of the poorest nations with a population of 25 million (the 52nd largest in the world). Trump went to denuclearize North Korea. And the statement shows commitment to that goal. As much as the Shanghai Communique shows commitment to any of their goals. Though in the Shanghai case, the two countries met, if not quite as equals, then as two of the most powerful nations on earth. And without any clear agenda items (such as the denuclearization goal) other than to establish contact and begin to regularize relations.

And here's the Shanghai Communique (as best as I can tell) issued jointly by China and the US after Nixon's visit in 1972.
203. Joint Statement Following Discussions With Leaders of the People’s Republic of China1Shanghai, February 27, 1972.President Richard Nixon of the United States of America visited the People’s Republic of China at the invitation of Premier Chou Enlai of the People’s Republic of China from February 21 to February 28, 1972. Accompanying the President were Mrs. Nixon, U.S. Secretary of State William Rogers, Assistant to the President Dr. Henry Kissinger, and other American officials.Optimistically, one could argue that Trump understood Kim as he understood the white working class in the US. He saw them as having a strong need for respect from others. A need that Trump himself seems to have. If he's right on this, perhaps being on equal footing the president of the United States will give him what he needs to stop his nuclear weapon program. It's possible. But as all but the most ardent Trump fans have been saying, there are no timetables, not concrete steps, no discussions of how to verify. It would be great if things progressed as Trump sees things. I'd be willing to acknowledge Trump did a great thing, if it works out. But there's a lot that can go wrong, not the least is Trump's twitter addiction. Some one night stands become more than that. But in most cases the glow fades quickly.
President Nixon met with Chairman Mao Tse-tung of the Communist Party of China on February 21. The two leaders had a serious and frank exchange of views on Sino-U.S. relations and world affairs.
During the visit, extensive, earnest, and frank discussions were held between President Nixon and Premier Chou En-lai on the normalization of relations between the United States of America and the People’s Republic of China, as well as on other matters of interest to both sides. In addition, Secretary of State William Rogers and Foreign Minister Chi P’eng-fei held talks in the same spirit.
President Nixon and his party visited Peking and viewed cultural, industrial and agricultural sites, and they also toured Hangchow and Shanghai where, continuing discussions with Chinese leaders, they viewed similar places of interest.
The leaders of the People’s Republic of China and the United States of America found it beneficial to have this opportunity, after so many years without contact, to present candidly to one another their views on a variety of issues. They reviewed the international situation in which important changes and great upheavals are taking place and expounded their respective positions and attitudes.
The U.S. side stated: Peace in Asia and peace in the world requires efforts both to reduce immediate tensions and to eliminate the basic causes of conflict. The United States will work for a just and secure peace: just, because it fulfills the aspirations of peoples and nations for freedom and progress; secure, because it removes the danger of foreign aggression. The United States supports individual freedom and social progress for all the peoples of the world, free of outside pressure or intervention. The United States believes that the effort to [Page 813]reduce tensions is served by improving communication between countries that have different ideologies so as to lessen the risks of confrontation through accident, miscalculation or misunderstanding. Countries should treat each other with mutual respect and be willing to compete peacefully, letting performance be the ultimate judge. No country should claim infallibility and each country should be prepared to re-examine its own attitudes for the common good. The United States stressed that the peoples of Indochina should be allowed to determine their destiny without outside intervention; its constant primary objective has been a negotiated solution; the eight-point proposal put forward by the Republic of Vietnam and the United States on January 27, 1972 represents a basis for the attainment of that objective; in the absence of a negotiated settlement the United States envisages the ultimate withdrawal of all U.S. forces from the region consistent with the aim of self-determination for each country of Indochina. The United States will maintain its close ties with and support for the Republic of Korea; the United States will support efforts of the Republic of Korea to seek a relaxation of tension and increased communication in the Korean peninsula. The United States places the highest value on its friendly relations with Japan; it will continue to develop the existing close bonds. Consistent with the United Nations Security Council Resolution of December 21, 1971, the United States favors the continuation of the ceasefire between India and Pakistan and the withdrawal of all military forces to within their own territories and to their own sides of the ceasefire line in Jammu and Kashmir; the United States supports the right of the peoples of South Asia to shape their own future in peace, free of military threat, and without having the area become the subject of great power rivalry.
The Chinese side stated: Wherever there is oppression, there is resistance. Countries want independence, nations want liberation and the people want revolution—this has become the irresistible trend of history. All nations, big or small, should be equal; big nations should not bully the small and strong nations should not bully the weak. China will never be a superpower and it opposes hegemony and power politics of any kind. The Chinese side stated that it firmly supports the struggles of all the oppressed people and nations for freedom and liberation and that the people of all countries have the right to choose their social systems according to their own wishes and the right to safeguard the independence, sovereignty and territorial integrity of their own countries and oppose foreign aggression, interference, control and subversion. All foreign troops should be withdrawn to their own countries.
The Chinese side expressed its firm support to the peoples of Vietnam, Laos, and Cambodia in their efforts for the attainment of their [Page 814]goal and its firm support to the seven-point proposal of the Provisional Revolutionary Government of the Republic of South Vietnam and the elaboration of February this year on the two key problems in the proposal, and to the Joint Declaration of the Summit Conference of the Indochinese Peoples. It firmly supports the eight-point program for the peaceful unification of Korea put forward by the Government of the Democratic People’s Republic of Korea on April 12, 1971, and the stand for the abolition of the “U.N. Commission for the Unification and Rehabilitation of Korea.” It firmly opposes the revival and outward expansion of Japanese militarism and firmly supports the Japanese people’s desire to build an independent, democratic, peaceful and neutral Japan. It firmly maintains that India and Pakistan should, in accordance with the United Nations resolutions on the India-Pakistan question, immediately withdraw all their forces to their respective territories and to their own sides of the ceasefire line in Jammu and Kashmir and firmly supports the Pakistan Government and people in their struggle to preserve their independence and sovereignty and the people of Jammu and Kashmir in their struggle for the right of self-determination.
There are essential differences between China and the United States in their social systems and foreign policies. However, the two sides agreed that countries, regardless of their social systems, should conduct their relations on the principles of respect for the sovereignty and territorial integrity of all states, nonaggression against other states, noninterference in the internal affairs of other states, equality and mutual benefit, and peaceful coexistence. International disputes should be settled on this basis, without resorting to the use or threat of force. The United States and the People’s Republic of China are prepared to apply these principles to their mutual relations.
With these principles of international relations in mind the two sides stated that:
—progress toward the normalization of relations between China and the United States is in the interests of all countries;
—both wish to reduce the danger of international military conflict;
—neither should seek hegemony in the Asia–Pacific region and each is opposed to efforts by any other country or group of countries to establish such hegemony; and
—neither is prepared to negotiate on behalf of any third party or to enter into agreements or understandings with the other directed at other states.
Both sides are of the view that it would be against the interests of the peoples of the world for any major country to collude with another against other countries, or for major countries to divide up the world into spheres of interest.
[Page 815]
The two sides reviewed the long-standing serious disputes between China and the United States. The Chinese side reaffirmed its position: The Taiwan question is the crucial question obstructing the normalization of relations between China and the United States; the Government of the People’s Republic of China is the sole legal government of China; Taiwan is a province of China which has long been returned to the motherland; the liberation of Taiwan is China’s internal affair in which no other country has the right to interfere; and all U.S. forces and military installations must be withdrawn from Taiwan. The Chinese Government firmly opposes any activities which aim at the creation of “one China, one Taiwan,” “one China, two governments,” “two Chinas,” and “independent Taiwan” or advocate that “the status of Taiwan remains to be determined.”
The U.S. side declared: The United States acknowledges that all Chinese on either side of the Taiwan Strait maintain there is but one China and that Taiwan is a part of China. The United States Government does not challenge that position. It reaffirms its interest in a peaceful settlement of the Taiwan question by the Chinese themselves. With this prospect in mind, it affirms the ultimate objective of the withdrawal of all U.S. forces and military installations from Taiwan. In the meantime, it will progressively reduce its forces and military installations on Taiwan as the tension in the area diminishes.
The two sides agreed that it is desirable to broaden the understanding between the two peoples. To this end, they discussed specific areas in such fields as science, technology, culture, sports and journalism, in which people-to-people contacts and exchanges would be mutually beneficial. Each side undertakes to facilitate the further development of such contacts and exchanges.
Both sides view bilateral trade as another area from which mutual benefit can be derived, and agreed that economic relations based on equality and mutual benefit are in the interest of the people of the two countries. They agree to facilitate the progressive development of trade between their two countries.
The two sides agreed that they will stay in contact through various channels, including the sending of a senior U.S. representative to Peking from time to time for concrete consultations to further the normalization of relations between the two countries and continue to exchange views on issues of common interest.
The two sides expressed the hope that the gains achieved during this visit would open up new prospects for the relations between the two countries. They believe that the normalization of relations between the two countries is not only in the interest of the Chinese and American peoples but also contributes to the relaxation of tension in Asia and the world.

CHINA, 1969–1972
But looking at the two documents, I'd say that the China one has more detail on a wider range of topics and is more diplomatic in its language, but there aren't any more specifics about the next steps and no deadlines. That peace on the Korean peninsula they both supported, well, it's 35 years later and we've been in one of the tensest periods in decades.
