Talks in Geneva aimed at liberalising world trade seem to be making some progress.
147 countries held discussions through the night in an attempt to resolve some of the key issues.
The talks which are focussing on farm subsidies and tariffs aim to get an outline deal on global free trade which could add some 520 billion dollars to the world economy by 2015.
Such a deal would deliver a framework which would allow formal talks, which fell apart in Cancun last year, to resume.
The Group of 90 of the WTO's poorest members have said they would accept a draft text on agriculture provided progress is made on industrial tariff cuts.
