Chinese automotive manufacturer Tri-Ring Group will buy Polish bearings maker FLT Krasnik for US$ 93 million (572 million yuan) in the largest investment yet by a Chinese firm in Poland, a person close to the deal said.

The purchase comes a year after former Premier Wen Jiabao set a target of doubling China's trade with Poland. "The investment is a result of the political discussions during Wen Jiabao's visit last year," the source said on 15th May.

Krasnik, which is 89 percent owned by state industry development agency ARP, employs 2,000 workers and has annual sales of some 379 million yuan.

ARP declined to comment. No one at Tri-Ring was immediately available for comment.

ARP chief Wojciech Dabrowski and several Krasnik officials visited Tri-Ring Group last month to discuss a possible purchase.

Tri-Ring manufactures special purpose and military vehicles and automotive components in China.
