Taiwanese Premier Sean Chen said Friday he has stepped down for health reasons, after the cabinet he heads came under fire for its poor handling of the economy. "I have some health problems ... and I need to completely change my life and work style to reverse the situation," the 63-year-old finance expert told a press conference to announce his resignation. "I believe that the economy will improve in the coming year. We have worked very hard on the planning for long-term issues and I hope everybody will continue to support the new team."
