Two years after the Sino-Soviet border conflict from 1969, a series of diplomatic means and probes between China and the United States convinced both sides that the reality of direct contact was ripe. After careful arrangements, Kissinger left Washington for Southeast Asia on July 1, arrived in New Delhi on June 6 and arrived in Islamabad on August 8. In order to balance India-Pakistan relations, he announced that he would also stay in Pakistan for two days. But in order to visit China secretly, he pretended to have a stomachache at the dinner party. President Yahya Khan specially invited Kissinger to rest in the presidential villa, thus getting rid of the reporters. In the early morning of the 9th, accompanied by Zhang and others, he flew directly to Beijing on a Pakistan civil aviation flight and arrived at Nanyuan Airport on the same day.
During Kissinger's two-day visit to China, he made many contacts with China. The two sides exchanged attitudes on Vietnam, Taiwan Province Province and Sino-US relations, and discussed Nixon's visit to China. It has played a very important role in the process of easing Sino-US relations and establishing diplomatic relations.
