China agreed to buy $200 billion more in U.S. goods (over 2 years) above 2017 levels.

The U.S. suspended some tariffs, but kept many in place.

It included IP protection, forced tech transfer, currency transparency clauses.

Yes, but context matters:

China bought far less than pledged — by end of 2021, they had only fulfilled ~57% of the purchase targets.

but anyway, china did sign the agreement to buy maybe china is dumb ?

that agreement did not stated end of the priod... so technical still an agreement
