It wasn't a Chinese ship. It was flagged in China, which is like buying a .US domain name when you don't live in the US. It's simple to do. The captain is Russian and the company who owns/operates the ship is headed by a Russian CEO. The crew was not Chinese either.
China didn't do it and the USA hasn't withdrawn from anything.
That would be the Chinese in Chinese ship.
