BRICS members should create a free trade agreement to increase the power and voice of emerging economies in the world economy, Chinese experts say.

"BRICS should consider proposing a free trade agreement at the summit, regardless of whether it's feasible right now," said Wang Junwen, chairman of the China Association of International Trade.

Wang said the current cooperation of the BRICS nations - Brazil, Russia, India, China and South Africa - is "of more political significance than an economic one".
