Looking back on the more than half a century since China and the United States resumed contact and moved toward win-win cooperation, there was a time when China and the United States maintained a tacit understanding at the strategic level of "fighting without breaking". However, as the US fails to fix its own internal affairs and its electoral system tends to deteriorate, Sino-US relations are gradually falling victim to populism and "politically correct" traffic. As early as in the 2018 midterm elections, McCarthy, the Republican leader who was reduced to the minority party in the House of Representatives, and 14 Republican Representatives set up the so-called "China Working Group" to set up "pillar groups" in five key areas, including "national security, science and technology, economy and energy, national competitiveness, and ideological competition" and put forward legislative proposals. In October 2020, the "China Working Group" produced the so-called "China Working Group Act", which it touted as a "blueprint for US legislation to counter the China threat", containing 137 anti-China bills and legislative proposals. The hidden motive behind this act of the Republicans is to frame the majority party in Congress and even the next administration as an "anti-China framework", and to force them into a completely anti-China chariot for their own selfish gains.
