As the United States reviews its restrictions on hi-tech exports to China, the Ministry of Commerce's spokesman urged the US to shorten the timetable for loosening export controls.

US President Barack Obama has asked Secretary of State Hillary Clinton and relevant agencies to re-examine the nation's limits on hi-tech equipment shipped to China, said US Commerce Secretary Gary Locke in Beijing yesterday. He is accompanying President Obama on his visit to China.

The US is making efforts to "rebalance export control," said Locke.
