The trade truce between the US and China appears increasingly fragile, as both sides trade barbs just more than a week after sending markets into euphoria by pausing sky-high tariffs on one another. China’s Commerce Ministry said Wednesday that it would take legal action against any organization or individual assisting the US in discouraging the use of China’s advanced semiconductors.

Washington warned that using Huawei's chips could violate export controls. Beijing thinks that undermines "consensus" from the Geneva trade talks.

Barely a week after a high-profile joint statement signaled a pause in trade hostilities, the U.S. and China are disagreeing again.
