Biden Urges China to Adhere to Agreement They Didn’t Enter

The ongoing tension in China continues to worsen. There are reports coming out that China is gearing up to launch a full-scale takeover of Taiwan in the coming years.
As tensions rise between China and Taiwan, President Biden addressed the situation, saying:
"I’ve spoken with [Chinese President] Xi about Taiwan. We agree . . . we will abide by the Taiwan agreement. We made it clear that I don’t think he should be doing anything other than abiding by that agreement."
There is nothing for him to abide by. The U.S. is a party to that agreement, but China is not.
