Since the normalization of relations between the People’s Republic of China and the United States, China, consistent with the normal practice of international relations, has traditionally engaged the US political system through the executive branch. In the past decade, however, China has initiated efforts to significantly deepen its relationship with Congress. The intensification of Chinese engagement with Congress is driven in part by a shift in the nature of economic relations between the two nations as Chinese entities seek to enter the US market, but is also attributable to a moderation in support from US corporations which have historically lobbied on China’s behalf. Despite China’s heightened engagement with Congress, its influence remains modest. Going forward, the risk of more volatile bilateral relations driven by hostile congressional actions would suggest the need for further cultivation of Sino-Congressional relations – not simply for China’s sake – but for that of the US as well.
