PAMELA SAMPSONBANGKOK (AP) â¿¿ Asian stock markets were mostly lower Wednesday as data suggesting a slowdown in China raised concerns that its economy might not have the momentum needed to help sustain a global recovery. In Japan, export-reliant companies like Toyota Motor Corp. felt pressure as the dollar gave up some of its recent gains against the yen. The Nikkei 225 index fell 0.2 percent to 10,120.63. South Korea's Kospi index dropped 0.3 percent to 2,035.34. In Australia, where economic growth is tightly bound to sales of its raw materials to China, the S&P/ASX 200 was 0.1 percent lower at 4,273.80. Benchmarks in Singapore and Indonesia also fell. Hong Kong's Hang Seng was flat at 20,885.39. Mainland Chinese shares rose. Worries over the pace of the slowdown in the world's No. 2 economy were fueled by comments Tuesday from mining giant BHP Billiton, which warned that Chinese demand for iron ore, which is used for making steel, was flattening. Analysts at Credit Agricole CIB in Hong Kong attributed a recent deterioration in investor sentiment to the slowdown in China. But they said China's growth should remain solid enough to exceed the government's target and "to support the region." "We believe that China is slowing but the deceleration will continue to be gradual," analysts said in an email. The weaker demand for iron ore hurt some of the region's major steelmakers. Japan's Nippon Steel Corp. fell 1.7 percent and JFE Holdings Inc. tumbled 2.5 percent. South Korea's POSCO shed 2.3 percent. In another sign of cooling growth in the world's No. 2 economy, new home prices dropped in 45 Chinese cities in February as the government implemented measures to cool property speculation. The rising cost of crude is also a threat to the global economic outlook as it could spark inflation and hurt consumer spending. On Tuesday, China raised the price of retail gasoline for the second time in two months.
