HELSINKI (AP) — Nokia Corp. said Tuesday it is axing 220 jobs at research and development units in Japan as the world’s largest mobile phone maker continues to cut costs.

Last week it announced 330 job cuts in Finland and Denmark at its R&D operations that globally employ 17,000 workers.

Nokia said it will continue “significant sourcing activities” in Japan.

“Japanese manufacturers are important partners who play a critical role in Nokia’s global supply chain strategy and with whom Nokia continues to develop its world-class logistics operations,” the Finnish company said.

The cuts will not affect Japanese operations of Nokia Siemens Networks, the company’s network infrastructure sector, nor Vertu, Nokia’s luxury handset line, the company said.

Nokia employs 123,350 people worldwide. Last year, it sold 468 million handsets, up 7 percent on 2007.
