Just one month after the Republican-led U.S. Senate rejected a nuclear test ban treaty, Japan is preparing to launch a new flurry of diplomacy aimed at keeping up international pressure on the United States and other declared and effective nuclear powers to ratify the treaty.

The government plans to dispatch Norio Hattori, the ambassador in charge of arms control, to Indonesia, Vietnam and Bangladesh as early as later this month to try and persuade the Asian countries to ratify the Comprehensive Test Ban Treaty, Foreign Ministry sources said Friday.
