China with Economic sanctions.

Explanation:

1-China / economic sanctions:

There's a lot of political conflict and economic sanctions that lead to more conflict between the U.S.A. and China right now as a consequence of this trade bogging down stuck in a commercial war with consequences to both countries where as far as I'm concerned (and in fact) yesterday  I've heard that The Chairman of USA said that this trade war was lost properly saying that they're losing it with no profits for the imbalance within import tariffs.
