HONG KONG, Aug 29 (Reuters) - Asia stocks rallied on Friday, led by industrial companies and exporters, after a big upward revision to second quarter U.S. economic growth boosted the outlook for demand, but shares were down for a fourth month.
The U.S. dollar slipped as oil prices climbed $1 as Tropical Storm Gustav with hurricane-force winds headed to the Gulf of Mexico, home to a quarter of U.S. crude production. Crude tumbled more than $2 overnight after the U.S. government promised to tap emergency stockpiles if needed.
Data overnight underscored the extent to which the U.S. economy -- the origin of the credit crisis plaguing the global financial system -- has outperformed Europe and Japan since March. This supported the U.S. dollar in August, setting it on track for its largest monthly rise against the euro since January 1997.
"After their latest sharp losses, shares are set for a modest rebound today, helped especially by rallies in U.S. shares and strong U.S. economic data," said Kim Seong-bong, a market analyst at Samsung Securities in Seoul.
"Worries about the credit crunch still exist and sentiment remains weak, but much of the concern has probably already been reflected in the losses we've seen this month."
Japan's Nikkei share average <
> rose 2 percent, lifted by shares of well-known overseas companies like Honda Motor Co <7267.T> and Canon Inc <7751.T>.Outside of Japan, stocks in the Asia-Pacific region <.MIAPJ0000PUS> were up about 1 percent, according to an MSCI index, which has remained in a very narrow trading range for the last two weeks because of a summer lull in trading volume.

Although the 15-nation currency has rebounded from a six-month low of $1.4570 hit on Tuesday, it has suffered a steep 5.7 percent decline in August after a series of weak economic data changed expectations for a European Central Bank interest rate rise this year.
"Even though inflation and inflation expectations have lessened across the G10 economies, the impetus is on the euro zone and other economies to seek more accommodative policy up ahead due to relative economic weakness," said Benedikt Germanier, currency strategist with UBS in Stamford, Connecticut.
The dollar slipped 0.3 percent against the yen <JPY=> at 109.13 yen, down from a 7-month high around 110.66 yen set two weeks ago.
