The logjam in world trade talks started to break on Friday, as rich and poor countries showed a bit more give-and-take over the reduction of subsidies paid to rich-country farmers.
Ministers face a weekend of marathon negotiations if they are to find enough common ground to revive hopes of concluding a new global trade pact by their self-imposed deadline of the end of next year. The Cancun talks are due to end today.
"There's a lot of activity and some indications of movement. I remain cautiously optimistic that we can get a really worthwhile agreement and progress here in Cancun," said Britain's trade secretary, Patricia Hewitt.
The World Bank estimates a deal to lower global trade barriers could add more than US$500 billion a year to global incomes by 2015, lifting 144 million people out of poverty.
The 4,700 delegates to the WTO talks realize that, with US elections next year and the EU preoccupied with the entry of 10 new members, failure now could scuttle chances of a deal for several years.
"I hope that Cancun turns out as an important turning point because this is an opportunity for developing countries to leave the imprint of their stance on the WTO," said Arun Jaitley, India's commerce minister. "If they miss this opportunity, the next will not come for decades."
A senior US official said talks with an assertive new alliance of 21 developing countries, led by heavyweights India, China, Brazil and South Africa, had been positive.
He said Singaporean trade minister George Yeo, who is trying to reconcile the many differing positions within the 146-member WTO, still faced a very tough task. But the official added: "Overall, we're still optimistic that this will all come together."
Thomas Aquino, the Philippine undersecretary for trade, struck a similar note: "Something will come out of this."
The Group of 21 developing countries has put pressure on the US, the EU and Japan by demanding rich countries slash about US$300 billion a year in agricultural subsidies.
The Group of 21 complains the subsidies shield farmers in wealthy countries and impoverish millions of their own farmers who are unable to compete with subsidized exports from the West.
Gregor Kreuzhuber, a spokesman for European Farm Commissioner Franz Fischler, cautioned that major differences remained and said there was no reason to be overly optimistic or enthusiastic.
But "certain glimmers of hope are appearing. Tomorrow is the day, tomorrow is the crunch day," Kreuzhuber said.
Ministers and officials planned to work late into the night to produce a compromise text that would provide the basis for a frenzied finale to the week-long negotiations.
"If the text is well-received, I hope we'll be sunbathing [today]," said Carlos Perez del Castillo, who heads the WTO's general council.
Agriculture is not the only make-or-break issue at Cancun.
Attempts by the EU and Japan to graft guidelines on foreign investment and competition onto world trade rules have run into fierce opposition from an array of developing states.
Jaitley and Malaysian trade minister Rafidah Aziz expressed the "firm view" on behalf of nearly 60 countries that negotiations on the proposed new rules were a non-starter.
Thousands of anti-capitalism activists have descended on Cancun, a swanky Caribbean beach resort, and were planning a big anti-WTO march yesterday.
