When we last left our gripping narrative about the Doha round, I asked a question without an answer:

ME: There seems to be a catch-22 on reviving Doha. Other countries won't negotiate seriously with the United States unless they believe that we can get TPA renewed. At the same time, the only way that TPA is likely to be renewed is if Congressmen seen the outline of a Doha deal. How does one escape this conundrum?

[USTR SUSAN] SCHWAB: Good question. [Long pause.]

The Doha round of global trade talks stalled after hitting numerous roadblocks over the summer. Now the White House is working to revive negotiations, even as a new barrier looms: a Congress much more skeptical of free trade.

Administration officials have stepped up the campaign to win support for its plan. Trade Representative Susan Schwab, who spent years as an aide on Capitol Hill, is wooing the incoming trade czars of the new Democratic Congress. Speaking recently to the U.S. Chamber of Commerce, she urged cooperation on trade and Doha. "We cannot let a strong, potential Doha deal slip through our fingers," she said.

Treasury Secretary Henry Paulson is rallying support for Doha around the globe. In London, he said Doha remains the administration's "top trade priority," even with the change in control of Congress next year. In Geneva, U.S. negotiators, after months on the sidelines, are taking part in fresh talks with trading partners on thorny issues, such as cutting farm supports.

The administration is banking that all the political maneuvering will help inject some momentum back into the talks by the spring. The goal isn't necessarily to finish a deal then, but to show enough progress to persuade skeptics in Congress to extend the president's trade-negotiating authority beyond June, when it is set to expire. That authority lets the president negotiate deals with other countries, and put them to Congress for an up-or-down vote -- without amendment. As a practical matter, nations generally don't like to sign deals that could be changed in Congress, so extending that authority would buy U.S. negotiators some extra time to seal a Doha deal.

Whether the Bush administration is able to restart the Doha talks could serve as a measure of the muscle behind critics of free trade in the U.S. And if the impasse on Doha becomes permanent, it could herald the closing of the era of global economic integration that began after World War II.

"A failure of Doha really would signal a crisis of confidence in the multilateral trading system," said C. Fred Bergsten, director of the Peter G. Peterson Institute for International Economics, a free-market think tank in Washington. "The WTO would continue to exist. But there would be a big loss of its standing and its credibility." (emphasis added)

With regard to Bergsten's prediction, I actually think the crisis of confidence is already upon us, if this Economist Intelligence Unit survey is any indication:

[T]he Economist Intelligence Unit conducted a wide-ranging survey of 286 executives spread across the world’s main trading regions. The key findings from the research are highlighted below.

Protectionism is thought to be on the rise, particularly in the developed world. Just over 50% of survey respondents thought that protectionism was rising either significantly or moderately in developed markets, with only 16% believing that it was falling (30% regarded the level of protectionism in those markets as stable). A smaller proportion, although still narrowly the majority, of respondents (39%) thought that protectionism was increasing in emerging markets, whereas one-third reckoned it was declining. In practice, while protectionism is difficult to track, its impact on growth is significant.

The impact on business can be severe... Economist Intelligence Unit forecasts show that a relatively modest backlash against globalisation could shave nearly a full percentage point off world GDP growth over the period 2011-2020. One in five executives to express a view (38 companies in total) say their company has had an investment deal fail in a certain market owing to local trade and investment rules over the past three years. More happily, 25% of the overall sample have entered a new market in that same period because of changes in the rules.
