The United States buys 16 fighter from China. When can China import from the United States?

The United States bought China fighter jets in the 1970s. The United States bought a batch of J-7Bs to simulate MiG -2 1 for imaginary enemy troops to train against the Soviet Union. China had a chance to buy American fighter planes. During the honeymoon period between China and the United States in 1980s, the United States promoted F- 16/J79 to China (the performance castrated version of F-16), but China could not accept the additional conditions of the United States (the United States helped China to build an electronic early warning system, deployed an E-3 early warning aircraft in China, and provided China with a monkey version of F-16). Moreover, China's air force did not participate in the combat mission against Soviet bombers, and the United States could directly send troops to China and China in case of war, so the project was finally dismounted. The Soviet Union disintegrated in the early 1990s, the honeymoon period between China and the United States ended, and the United States imposed an arms embargo on China, so it is impossible to buy fighter planes from the United States now.
