President Richard Nixon visits the People’s Republic of China. After arriving in Beijing, the president announced that his breakthrough visit to China is “The week that changed the world.” In meeting with Nixon, Prime Minister Zhou Enlai urged early peace in Vietnam, but did not endorse North Vietnam’s political demands. North Vietnamese officials and peace negotiators took a dim view of Nixon’s trip, fearing that China and the United States would make a deal behind their backs. Nixon’s promise to reduce the U.S. military presence on Taiwan seemed to confirm North Vietnam’s fears of a Chinese-American sellout-trading U.S. military reduction in Taiwan for peace in Vietnam. Despite Hanoi’s fears, China continued to supply North Vietnam levels of aid that had increased significantly in late 1971. This aid permitted the North Vietnamese to launch a major new offensive in March 1972.
