Asia Pacific markets traded mixed on Thursday after data showed growth in China's industrial output fell. Overnight, British lawmakers rejected the idea of leaving the European Union without a Brexit deal in place. The Nikkei 225 in Japan gave up its gains to finish flat at 21,287.02 while the Topix index fell 0.24 percent to 1,588.29. In South Korea, the Kospi wavered between gains and losses to close up 0.34 percent at 2,155.68. Hong Kong's Hang Seng Index was down 0.22 percent in afternoon trade. Chinese mainland shares withdrew as the Shanghai composite fell 1.2 percent to 2,990.68 while the Shenzhen composite tumbled 2.311 percent. Data on Thursday showed China's industrial output growth fell to a 17-year low in the first two months of the year, according to Reuters. That further pointed to an economic slowdown in the world's second-largest economy. But investments picked up pace as the government fast-tracked more road and rail projects, the news agency added. Beijing has already pledged hundreds of billions of dollars in tax cuts and infrastructure spending to support the flagging economy. The on-shore yuan traded at 6.7134 to the dollar at 2:44 p.m. HK/SIN after the People's Bank of China set the day's yuan midpoint at 6.7009. China's central bank allows the currency exchange rate to rise or fall 2 percent from the midpoint rate. Australia's benchmark closed up 0.3 percent at 6,179.60.

Brexit talks

Investors became optimistic when U.K. lawmakers rejected the idea of leaving the EU without a deal in place under any circumstance. Initially Prime Minister Theresa May's government had asked Parliament to vote on ruling out a no-deal Brexit for the official Mar. 29 deadline. The passing of the amended motion has severely undermined May's authority and could potentially lead to ministerial resignations, some analysts said. The British pound traded around $1.3271 at 2:45 p.m. HK/SIN after previously surging around 2 percent against the greenback to $1.3339 following the U.K. parliament vote — it was the biggest move since April 2017. Wednesday's vote to reject a no-deal Brexit "does not remove the risk of a disorderly Brexit on March 29," analysts at Singapore's DBS Group wrote in a Thursday morning note. "The pound's appreciation yesterday is still set on shaky and not on firm foundation."

Members of the U.K. parliament will vote again Thursday evening to seek an extension to Article 50, which oversees the withdrawal process from the EU, thus extending the departure date beyond Mar. 29. The EU would have to agree to this and the U.K. would need to give a good reason for requesting such a delay.
