Off-limits sectors up for review

More time is needed for the revision of China's "negative list" - sectors that would remain closed to US investment - in the negotiations for a bilateral investment treaty, a senior trade official said on Monday.

"Both sides are working closely to push for positive progress," said Zhang Xiangchen, vice-minister of commerce.

Zhang, at a news conference on the sidelines of the eighth US-China Strategic and Economic Dialogue in Beijing, said that China hopes the negotiations will achieve a win-win result.
