The letter said "Congressional approval of PNTR for Vietnam is necessary for the US business community to take full advantage of the benefits that will be granted to all World Trade Organisation (WTO) members after Vietnam's accession."

"Without PNTR, the US will be the only WTO member country that will not have access to new market openings for goods and services."

"With a young and vibrant population of 83 million, Vietnam is one of the fastest growing economies in the world and is the fastest growing market for US products in Asia.

"Upon joining the WTO, Vietnam will eliminate domestic subsidies, cut tariffs and reduce trade barriers on a wide range of US manufactured goods, farm products and services.

"WTO membership also compels Vietnam to abide by international laws and practices, and thereby, levels the playing field to enable American companies and products to compete more effectively. Vietnam’s joining the WTO will present great opportunities for American businesses, workers, farmers and consumers."

The coalition's letter also said that timely approval of PNTR is essential not only to US business interests and the overall US trade agenda, but also to US foreign policy interests.

With President George Bush scheduled to visit Vietnam this November during the APEC Economic Leaders' Meeting, this is a critical time for the US Congress to show support and initiate a significant step forward in the US-Vietnam relationship, stressed the letter.

At a press conference with US Trade Representative Susan Schwab on June 23, Congressman Joy Blunt said the US House of Representatives may approve the Free Trade Agreement (FTA) with Oman, Peru and Vietnam this year.

He also expressed his hope that the US Congress will approve the agreement to pave the way for Vietnam's WTO accession before President Bush's visit in November.
