A recent encouraging rally of Chinese imports was a bright spot in what has otherwise been a flop in the U.S.-China Phase 1 trade deal.

A deputy U.S. trade representative said last week that it is clear China hasn’t met their commitment in Phase 1 and that the Biden administration is working with Chinese officials to address the issue. U.S. officials have also commented they’re losing patience over China’s failure to close the shortfall in its purchase commitments.
