Asian equities were mostly in the red on Wednesday amid mounting geopolitical risks in the region and rising expectations that the Federal Reserve would tighten monetary policy next week.
The Japanese benchmark Nikkei 225 closed down 0.47 percent or 90.1 points at 19,254, its third straight session of losses. Japan's fourth-quarter gross domestic product was revised up to 1.2 percent from the preliminary figure of 1 percent, as capital expenditure grew at its fastest pace in three years.
Australia's ASX 200 was off 0.03 percent or 1.73 points to close at 5,759.7, with heavy losses in its materials sub-index, which was down 0.81 percent.
Mainland Chinese markets finished mixed after it produced a rare trade deficit in yuan terms. Earlier, official data showed that exports in yuan-denominated terms had risen 4.2 percent from a year earlier, but imports advanced 44.7 percent year-on-year.
Hong Kong's Hang Seng index was up 0.36 percent.
South Korea's Kospi was up just 0.06 percent or 1.4 points at 2,095.4 as traders eyed the expected Constitutional Court's announcement about whether it will deliver it ruling on the President Park Geun-hye's impeachment, Reuters reported.
Geopolitical risks in Asia are mounting, with the arrival of the first components of a U.S.-deployed Terminal High-Altitude Area Defense (THAAD) anti-missile system in South Korea.
The deployment of the system drew strong rebuke from China, even though the U.S. state department said it has told China that the deployment of the THAAD anti-missile system is no threat, but a response to North Korea's latest missile test.
South Korean companies in China have since reported cyber attacks, store closures and fines, while state-controlled media has called for a boycott of South Korean goods and services, Reuters reported.
