I think shoehorning an old concept like a "cold war" into our present situation is a little bit fraught, and assumes that China is driven by motivations similar to those that drove the old Soviet Union after WWII and the United States in the same period. Also assuming that a cold war won't turn hot because nobody can afford it assumes that government officials are perfectly rational and have perfect judgement, which to me seems damned unlikely.
The United States in 2021 is not the United States of 1948
