hina's foreign minister on Wednesday took a swipe at the United States' trade policy and defended international free trade on the basis of World Trade Organisation regulations.

"Trade unilateralism goes against the current of history," Wang-Yi said alongside his French counterpart Jean-Yves Le Drian speaking through an interpreter. "We must preserve international free trade on the basis of WTO rules."

The two foreign ministers also agreed to the need to maintain the Iran nuclear deal.
