Shares in Asia fell on Tuesday as readings on China's manufacturing activity failed to meet expectations, underscoring weakness in the world's second-largest economy despite Beijing's attempts to spur growth.
Both official and private business surveys pointed to slower Chinese factory growth this month, dashing hopes for a steady reading or even a faster expansion. Data also showed a slower expansion in its services sector, adding to economic uncertainty.
The dollar-denominated MSCI index of Chinese shares dropped 0.8 percent. But Chinese blue chips in Shanghai and Shenzhen kept losses in check, losing less than 0.1 percent as investors maintained hopes for further measures to prop up the economy.
The weak manufacturing numbers suggest "stimulus is there to stay," said Frances Cheung, head of macro strategy for Asia at Westpac. Upbeat data for March had prompted some analysts to scale back expectations of additional support measures.
MSCI's broadest gauge of Asia-Pacific shares outside Japan was off 0.7 percent. Korean shares led losses for the region, falling 1.3 percent.
Australian equities fell 0.6 percent.

Even before the China data, Asian investors had shrugged off cautious gains on Wall Street overnight that had lifted the S&P 500 index to an intraday record high of 2,949.52. The index finished up 0.11 percent at a record closing high of 2,943.03.
The Nasdaq gained 0.19 percent to 8,161.85, also a record closing high, and the Dow Jones Industrial Average eked out a 0.04 percent gain to 26,554.39.
The quiet start to the week in global equity markets comes ahead of a two-day meeting of the policy-setting Federal Open Market Committee. The committee is set to release its latest statement at 2 p.m. EDT (1800 GMT) on Wednesday.
The Fed is widely expected to leave interest rates unchanged, as it seeks to balance robust economic growth against low inflation.
In the latest slew of data sending mixed signals to the Fed, U.S. consumer spending rose at the fastest pace in more than 9-1/2 years in March, but core personal consumption expenditures (PCE), the bank's favoured inflation measure, logged its smallest annual rise in 14 months.
"We expect the dovish tone from central banks to continue for the foreseeable future. Given evidence of a recovery in growth, this is very positive for risk assets," analysts at ANZ said in a morning note.
The yield on benchmark U.S. 10-year Treasury notes retreated to 2.527 percent as of 2330 GMT Tuesday after rising to a close of 2.536 percent Tuesday on the strong consumer spending data.
The two-year yield, watched as a gauge of expectations of rate rises, was at 2.2942 percent in late New York trades, off from a U.S. close Tuesday of 2.298 percent.
In the currency market, the dollar lost 0.05 percent against the yen to 111.55, and the euro was barely changed at $1.1184.
The dollar index, which tracks the greenback against a basket of six major rivals, was also unchanged, holding at 97.852.
While other currencies remained stable, the dollar jumped 0.4 percent against the Korean won, to 1,163.33.
"The won is both risk- and trade-sensitive, and as such it is suffering," said Cheung at Westpac.
"Upward pressure on USD/Asia is likely to stay before we see some economic improvement (in China)," she added.
