China and the United States agreed Wednesday to strengthen cooperation on infrastructure while calling for an acceleration of talks on a bilateral investment treaty.

"This year's dialogue led to new consensus on infrastructure investment between China and the US," Chen Wenling, chief economist at the China Center for International Economic Exchanges, said at the closing of the Sixth Annual US-China CEO and Former Senior Officials' Dialogue, held in Beijing this week.

"Both sides agreed there are tremendous investment opportunities and huge potential, and urged the governments to conclude the bilateral investment treaty negotiations as soon as possible," Chen said.
