SHANGHAI, March 1 (Reuters) - Asian shares rose on Friday, driven by a rally in Chinese markets after index publisher MSCI announced it would boost the proportion of mainland shares in its global benchmarks, while strong U.S. economic data helped the dollar higher.
Chinese shares rallied, with the blue-chip CSI300 index .CSI300 adding 1.2 percent after MSCI said it would quadruple the weighting of mainland shares in its global benchmarks later this year, potentially drawing more than $80 billion of fresh foreign inflows to the world's second-biggest economy. along with strength in other markets in the region, helped push MSCI's broadest index of Asia-Pacific shares outside Japan .MIAPJ0000PUS up more than 0.3 percent.
The boost in mainland stocks on Friday follows a strong run for Chinese shares, which posted their strongest month in nearly four years in February, largely driven by investor hopes for government stimulus and policy support, as well as optimism over U.S.-China trade talks.
"Just two months ago China was facing one of the worst years it's ever had in terms of equity market performance. So I think investors are taking very seriously the fact that the rebalancing of MSCI is happening," said Jim McCafferty, head of equity research, Asia ex-Japan at Nomura.
"There's a disconnect between China's place in the world economy and China's place in the world's stock markets. And the two things can't be diverged for so long," he said.
Elsewhere in the region, Japan's Nikkei 225 .N225 gained 0.9 percent, helped by a weaker yen, while Australian shares .AXJO added 0.6 percent.
The gains in Asia contrast with a weaker finish on Wall Street on Thursday. The Dow Jones Industrial Average .DJI fell 0.27 percent to 25,916 points, the S&P 500 .SPX lost 0.28 percent to 2,784.49 and the Nasdaq .IXIC dropped 0.29 percent to 7,532.53.
U.S. President Donald Trump on Thursday fuelled concerns over trade talks between the United States and China, warning that he could walk away from a trade deal with China if it were not good enough.
But in subsequent comments Thursday, White House economic adviser Larry Kudlow called progress in the negotiations "fantastic" and said the countries were "heading towards a remarkable, historic deal." messages on trade combined with the collapse of the summit between U.S. President Donald Trump and North Korean leader Kim Jong Un on denuclearization, and data from China showing slowing factory activity to pressure U.S. stocks. that President Trump walked out of the meeting with Supreme Leader Kim, because the two sides couldn't reach an agreement over North Korea's nuclear disarmament, dashed hopes for an easing in geopolitical tensions," analysts at ANZ said in a morning note.
South Korea's financial markets are closed Friday for a public holiday.
