The retailer is moving into Shandong and Fujian provinces and said it would open more stores next year in Liaoning where Tesco has its base in China.
Tesco said like-for-like sales in China grew 8% in the 10 weeks to 1 November, compared with 14% in the first six months of the year. Malaysia was up 2% in the same 10-week period compared with 1% in the first half of 2008. South Korean sales fell 2% in the 10 weeks to 1 November, compared with a flat performance in the first half of the year.
"Management structures and the infrastructure are in place to drive a step-up in store openings," said Shore Capital analyst Clive Black. He added the opening programme would rise from about 10 per year to 30 "over an unspecified time frame".
