BEIJING - A US trade delegation wants China to cut a bilateral trade imbalance immediately and to stop subsidizing advanced technology, a Wall Street Journal reporter wrote on Twitter on Friday, citing a document issued to the Chinese before talks. In the document, the United States asked China to reduce its trade surplus with the US by $200 billion by 2020 and to cut tariffs on all products to levels no higher than those of the US, according to the tweet. A US trade delegation is in Beijing this week to discuss a wide range of US complaints about China's trade practices, from accusations of forced technology transfers to state subsidies for technology development.
