Japan said Tuesday it would give up to five billion dollars in new aid to Afghanistan over the next five years to help rebuild the war-torn nation. The announcement came just ahead of US President Barack Obama's visit to Tokyo on Friday and Saturday. "We will offer aid of up to five billion dollars over five years," the government said in a statement after the cabinet of centre-left Prime Minister Yukio Hatoyama approved the package. Since coming to power in September, the Hatoyama government has said it will end a naval refuelling mission that has supported the US-led campaign in Afghanistan, but instead promised to step up aid. The five billion dollars is likely to be disbursed through international organisations such as the UN Development Programme, said media reports.
