China and the United States should speed up negotiations to resolve thorny issues in areas such as national treatment in government procurement in order to reach a bilateral investment treaty, experts said on Monday.

Their comments came after the Ministry of Commerce announced on Sunday that treaty negotiations had made significant progress.

"China and the US should complete BIT negotiations before November's US presidential election to prevent potential political intervention," said Li Guanghui, vice-president of the Chinese Academy of International Trade and Economic Cooperation in Beijing.
