Japanese Prime Minister Junichiro Koizumi has told Mr Bush that Tokyo is ready to help rebuild war-torn Afghanistan as part of the campaign against terrorism. ''Regaining political stability and rebuilding the economy in Afghanistan is a necessary process in the initiative to eradicate and prevent terrorism,'' Mr Koizumi said after a half-hour meeting with Mr Bush. ''I told [Mr Bush] that Japan is able to play a role in rebuilding Afghanistan.'' Japan, whose military help in Washington's war on terrorism is limited by its constitution, is keen to play other roles such as restoring political stability and rebuilding the economy in Afghanistan after the military action is complete. Japan has also offered US$40 million (HK$311 million) to Pakistan to help with refugees and has frozen financial assets that the US believes are linked to terrorism. The Japanese Prime Minister and other officials did not give details of the extent of Japan's contribution to Afghanistan's reconstruction. Mr Bush welcomed the proposal, telling Mr Koizumi he hoped to see Japan do more than simply be a donor nation, according to Japanese officials. Mr Bush also expressed appreciation for Tokyo's support for the US-led global coalition to fight terrorism. Mr Koizumi said he had been briefed on the status of US military strikes in Afghanistan. According to Japanese officials, Washington said its military actions so far had been proceeding smoothly for the most part. Japan has been keen to portray itself as a reliable US ally. It is about to enact a controversial bill that will allow the military to provide non-combat support for the action against terrorism. Japanese officials said Tokyo could play a role in transport and providing medical services. An expanded overseas role for Japan's military would be a departure from the chequebook diplomacy Tokyo practised during the 1991 Gulf War, when it was criticised for not sending even a token force.
