China on Friday accused U.S. officials of lying to the public about their trade war, as rising tensions between the world's two largest economies kept financial markets in a state of unease.

Talks to end the trade dispute collapsed earlier this month, with the two sides in a stalemate over U.S. demands that China change its policies to address a number of key U.S. grievances, including theft of intellectual property and subsidies for state enterprises.

Washington has slapped higher tariffs on $200 billion in Chinese goods, prompting Beijing to retaliate, and effectively banned U.S. firms from doing business with Huawei Technologies Co., the world's largest telecom network gear maker.
