USA wants china to stop trading with russia. Russia is china's biggest trading partner. USA should be happy china is not shipping weapons directly to russia. China is no longer the largest trading partner with USA while china is russia's largests trade partner. USA imposes tariffs and want to decouple with china economically. USA is sanctioning china on computer chips. USA punishes china while russia cozy up to china. Obviously, USA should be happy china is not directly shipping weapons to russia. But to ask china to stop trading with russia is stupid. If usa is too forceful, then china can ship and sell weapons to russia, which is not something americans want.
