LIMA, Peru — Leaders from 21 Pacific Rim nations plan to issue a joint declaration during a summit this week promising to reactivate the stalled Doha round of world trade talks, a U.S. official said Tuesday.

Patricia M. Haslach, head of the State Department's Asian Pacific Economic Cooperation forum division, said President George W. Bush plans to personally lobby for the revival of the embattled trade negotiations.

World leaders launched the Doha round of World Trade Organization talks seven years ago in hopes of reducing trade barriers globally but the talks hit what was seen as an irreparable snag in July.

Countries like India and Brazil, fearing it would gut their agriculture sectors, rebuffed an offer from the U.S. and Europe to gradually reduce their farm subsidies in exchange for lower tariffs on food stuffs in emerging markets.

Haslach told reporters in Peru's capital, Lima, that a second declaration at the APEC summit will address the world's current financial situation and the "real urgency that we need to conclude" the trade talks.

The announcement comes on the heels of a declaration Bush obtained during Saturday's Washington financial summit, which brought together heads of state from the G-20 body of industrialized democracies and emerging economic powers.

The Washington declaration included a promise by the heads of state to do their best to wrap up an "ambitious and fair" agreement on the accord by the end of this year.

Haslach declined to give a tentative date for the conclusion of the trade round, since negotiations will be in the hands of U.S. trade representative Susan Schwab, who arrives in Lima on Wednesday.

APEC members China, Russia and Mexico will be in Lima this week to discuss trade, but major players, including Brazil, India and the European Union, will be absent.
