Washington: For the success of the Doha round it is vital that emerging economies like India, China and Brazil should open up their market more than what they are proposing right now on the negotiation table, a top US trade official has said.

"Doha can only reach this potential if key partners like China, India, and Brazil are willing to recognise their success as exporting powers by agreeing to open their markets to a degree much greater than what is currently on the negotiating table," the US Trade Representative, Ron Kirk, said on Wednesday.

"The gaps remain large, but the United States is working with our partners to try to find solutions," Kirk said in his address to the annual trade symposium of the US Customs and Border protection.

Kirk said that the Obama Administration was continuing to work hard to achieve trade successes at the multilateral level.
