Both sides faced domestic pressures against closer relations. A conservative faction of Republicans led by Barry Goldwater and Ronald Reagan strongly opposed a rapprochement with China, while Lin Biao led a similar faction in the PRC. For the first two years of his presidency, Nixon and China each made subtle moves designed to lower tensions, including the removal of travel restrictions. The expansion of the Vietnam War into Laos and Cambodia hindered, but did not derail, the move towards normalization of relations. Due to a misunderstanding at the 1971 World Table Tennis Championships, the Chinese table tennis team invited the U.S. table tennis team to tour China. In the aftermath of the visit, Nixon lifted the trade embargo on China. At a July 1971 meeting with Chinese Premier Zhou Enlai, Kissinger promised not to support independence for Taiwan, while Zhou invited Nixon to China for further talks. After the meeting, China and the United States astounded the world by simultaneously announcing that Nixon would visit China in February 1972. In the aftermath of the announcement, the United Nations passed Resolution 2758, which recognized the PRC as the legitimate government of China and expelled representatives from the ROC.
