China's share market and the yuan bounced on Monday despite heightened trade tensions between Washington and Beijing after each imposed major tariffs on the other's goods last week and investors nervously watched for more policy action. Monday's equities rally was seen driven by technical factors and government rhetoric to boost market confidence, but traders and analysts said the rise could be fleeting as a trade war with the United States will hit China's economy and global growth. "The rally is in part due to marginal improvement in liquidity conditions...and also thanks to a 'warm breeze' from regulators and top officials that helped lift market sentiment," said Zhou Yu, analyst with Pacific Securities.
