RIO DE JANEIRO, Nov. 12 (Xinhua) -- Brazilian President Luiz Inacio Lula da Silva Monday reinforced the need to reach an agreement on agriculture, urging developed nations to contribute more to the global trade talks.

    In a phone conversation with British Prime Minister Gordon Brown, Lula said the concessions should be made based on each country's capacity, and the developed nations would have to make a bigger contribution than developing ones, said Brazilian Foreign Minister Celso Amorim.

    The Brazilian government does not intend to block the World Trade Organization (WTO)'s Doha Round talks, but looks forward to negotiations, said Amorim.

    The G-20 developing nations will hold a meeting Wednesday in Geneva to discuss proposed changes to tariffs on farm and industrial goods, the major barrier blocking the Doha talks.

    During the meeting, an "ambitious and equilibrated" result is expected to be achieved, Amorim said.

    The Doha talks, launched in 2001, are aimed at lowering barriers in global trade and helping poor countries' development. But negotiations have stalled due to sharp differences between major WTO members on agricultural, trade and industrial market access.

    In the talks, developing countries want the United States to cut its farm subsidies, while Washington and the European Union want developing countries to cut industrial tariffs.

    Lula said in October that developing countries would not sacrifice industries for agricultural development because it might risk gaining nothing.
