UNITED NATIONS - China vowed to step up its fight against global poverty on Wednesday as it announced reductions and relief for the world's least developed countries from their debt burden.

Premier Wen Jiabao made the pledge during the UN's high-level plenary meeting of the General Assembly on Millennium Development Goals (MDGs).

He also promised to offer another $200 million in emergency flood aid to Pakistan in addition to the $47 million China has already sent to disaster areas in humanitarian assistance.
