Chinese machinery group LiuGong has struck a deal with unions at Poland's bulldozer firm HSW, paving the way for China's largest takeover in the country, a Polish newspaper reported Thursday.

The daily Rzeczpospolita said LiuGong had offered state-controlled HSW's 2,000 employees a four-and-a-half year job guarantee, a three-percent pay hike and a privatisation bonus.

The Polish state owns 80 percent of HSW, which is based in the southeastern city of Stalowa Wola.

The 250-million-zloty (57-million-euro, $76 million) deal would be the biggest ever takeover in Poland involving Chinese investors.

LiuGong is also planning to create a European research, development and distribution centre at Stalowa Wola, and also set up other production sites, Rzeczpospolita reported.

That could lift its total investment to 1.2 billion zloty, the newspaper said.

It was not immediately possible to confirm the report with HSW.
