"Your father was partners with Hyman Roth, he did business with Hyman Roth, but your father never trusted Hyman Roth."
Countries aren't people and shouldn't be treated as such. Countries operate according to their national interests, not according to "trust" and "loyalty" and other assorted nonsense.
It is not in the interests of China or the United States to be "enemies," and, as a consequence, they aren't.
