US President Donald Trump accused China of violating an agreement with the US to ease tariffs, escalating tensions between the two countries.
Trump's comments sparked fresh turmoil for his trade agenda, following a federal court ruling that halted the bulk of his tariffs.
US Trade Representative Jamieson Greer mentioned concerns about China's slow compliance with the agreement, particularly regarding critical minerals and rare Earth magnets.
The agreement between US and China earlier this month had initially boosted investor confidence, but tensions have resurfaced with new visa restrictions and export bans on technology.
