China's Tri-Ring signed Monday an agreement to buy Polish bearings maker FLT Krasnik, the second largest Chinese investment in Poland, its industrial development agency said.

The group signed the accord with Poland's treasury to buy the ARP agency's 89.15 percent stake, ARP spokeswoman Roma Sarzynska-Przeciechowska told AFP.

The takeover comes a year after then Chinese Premier Wen Jiabao pledged to double bilateral trade turnover with Poland over five years.

Sarzynska-Przeciechowska refused to disclose how much Tri-Ring would pay for the stake but said it was less than the roughly 56 million euros ($72 million) spent last year in China's largest investment in the EU member.

Chinese machinery group LiuGong bought Poland's bulldozer firm HSW as well as its distribution branch Dressta in that acquisition in January of last year.

Tri-Ring is one of China's leading bearings makers and among its 500 largest firms.

The Krasnik factory in eastern Poland has 2,000 employees and reported 265.3 million zloty (64 million euros, $82 million) in revenue last year.
