New York:US President George Bush has calledfor successful conclusion of Doharound trade negotiations, saying it provides the 'most promising opportunity'to expand free and fair trade and advised Americans against taking shelter inprotectionism in the face of globalization.

Addressing business leaders here yesterday, he also sought from the lawmakersthe authority to negotiate complicated trade deals and then send them to theCongress for tan up and downv vote agreement.

But analysts said Bush would not find it easy to get such a blanket authority,which expires later this year, from the Democratic Congress.

At the moment, Bush said, the most promising opportunity to expand 'free andfair' trade is conclusion of the Doharound with potential to lower trade barriers all around the world.

"Successful trade talks will have an enormous impact on the people aroundthe world. Since the World War II, the opening of global trade and investmenthas resulted in income gains of about USD 9,000 a year for the averageAmerican," he said.

The talks have been stalled over rich countries, including the United States,reluctance to end farm subsidies which would make agricultural products fromdeveloping world competitive. However, they insist that developing countriesopen up their markets to the products of the rich countries.
