     Toyota Motor Corp, Japan's biggest carmaker, said on Friday it will recall 1,489 Lexus sedans (高级轿车) sold in China. "It will take us some time to ship the fuel tanks and vent pipes to China to change

those in these Lexus sedans for customers free of charge, if problems are found," said Yang Hongjian, a

spokes- woman of Toyota's China representative office.

     The expected recall will affect Lexus LS430 sedans made in Japan from July 29, 2003 to January 14,

2004, the representative office said in a statement. Toyota has not received complaints from Chinese

customers, according to the statement. The move will be part of Toyota's global recall of 18,200 Lexus

LS430s. It will be the third car recall in China in two weeks. Although automobile recall is a common

practice in developed markets, it remains new to Chinese customers. The Chinese government published

long-awaited automobile recall rules on March 15, which will be officially carried out at the beginning of

October.

     China's auto market is forecast to reach 10 million units by 2010. Automakers, especially Chinese

producers, will face greater pressure from automobile recalls, which could be very costly sometimes, and

should be in full preparations, according to the expert. The Japanese carmaker sold 1, 549 Lexus

vehicles on the Chinese mainland during the first five months of this year, according to Yang. Lexus sales

on the mainland reached 4,000 units last year, up from 1,600 units in 2002. (China Daily July 3, 2004)
