Asian stocks rallied on Monday as positive Chinese factory gauges and signs of progress in Sino-U.S. trade talks supported sentiment, although another defeat for British Prime Minister Theresa May's proposed Brexit deal added to sterling's woes.
MSCI's broadest index of Asia-Pacific shares outside Japan added 1 percent and the Shanghai Composite Index rallied 1.7 percent.
Australian stocks climbed 0.8 percent, South Korea's KOSPI gained 1 percent and Japan's Nikkei advanced more than 2 percent.

A private business survey, the Caixin/Markit PMI, released on Monday also showed the manufacturing sector in the world's second biggest economy returning to growth.

"Our view is the impact of policy easing is gradually kicking in, pushing up sequential growth indicators such as PMI first," wrote China economists at Bank of America Merrill Lynch.
"In particular, the larger-than-expected tax and fee cuts and improving financial conditions have likely helped boost business sentiment in the manufacturing space."
