Asian stocks rose on Wednesday following better-than-expected Chinese trade data and as investors cheered Federal Reserve Chair Janet Yellen's reassurance of supportive U.S. monetary policy.
Mainland exports grew an annual 10.6 percent in January, compared to expectations for a 2 percent gain, but many attributed the figures to distortions from the Lunar New Year holidays.
Yellen stressed continuity in monetary policy in her testimony before the House Financial Services Committee, which saw the post triple-digit gains.
News that U.S. lawmakers have agreed to raise the U.S. debt ceiling without any add-on provisions also boosted sentiment. That announcement came after the close on Wall Street.
Nikkei up 0.5%
Japan's benchmark index resumed trade at a near two-week high after being shut on Tuesday for a public holiday. A weaker currency overshadowed disappointing economic data as the yen traded near a two-week low against the dollar, boosting exporters.
Among top gainers, Nissan Motor rose 2 percent after reporting its steepest quarterly profit gain in three years on Monday. Sony jumped 3.7 percent after the Nikkei reported it is in talks with Apple to double its supply of camera components for a new iPhone.
Meanwhile, December core machinery orders fell 15.7 percent from November, worse than the 4.1 percent expected fall.

"We're calling this year the 'Year of the Donkey.' We think China's growth will disappoint but we think old economy stocks will do better. There's a lot of blind buying of new economy stocks but all those sectors have high regulatory risks, whether its healthcare, media or the environment," said Ewin Sanft, head of China & HK equity research at Standard Chartered.
