US and Chinese negotiators have ended two days of meetings without reaching a breakthrough in a trade dispute between the world's two biggest economies that has disrupted global commerce.
The delegations "exchanged views on how to achieve fairness, balance and reciprocity in the economic relationship," Lindsay Walters, a White House spokeswoman, said in a statement on Wednesday that did not mention further talks.
The dispute over China's high-tech industrial policy has escalated, with the US and China taxing an additional $US16 billion ($A21.8 billion) of each other's goods.
This follows a US move last month to slap tariffs on $US34 billion in Chinese products, after which Beijing responded in kind.
The US is readying tariffs on $US200 billion more of Chinese products, and China has vowed to counterpunch by targeting $US60 billion in American goods.
