日本承诺提供1550万美元，帮助中东和非洲国家抗击伊斯兰国激进分子。
日本外务大臣岸田文雄星期二说，这笔援款将用于支持反恐努力，包括加强边境控制和调查能力。
日本外务省发表声明说，在华盛顿星期四召开的国际反恐会议上，日本副外相中山泰秀将公布有关这项援助的细节。
中山泰秀上月在访问布鲁塞尔期间曾承诺提供援助，而周二宣布的反恐援助数额是上月承诺的两倍。此外，东京还承诺提供两亿美元，帮助逃离伊斯兰国控制地区的难民。
日本首相安倍晋三誓言对伊斯兰国激进分子做出强硬反应。今年1月，伊斯兰国激进分子将两名日本人质斩首。
Japan has pledged $15.5 million to help countries in the Middle East and Africa that are battling militants from the Islamic State group.
Tokyo's Foreign Minister Fumio Kishida said Tuesday the aid would support counter-terrorism efforts, including increased border control and investigation capabilities.
More details of the aid will be unveiled by Vice Foreign Minister Yasuhide at an international anti-terror conference Thursday in Washington, a foreign ministry statement said.
The counter-terrorism package is twice the amount previously pledged by Kishida during a visit to Brussels last month. Separately, Tokyo has also pledged $200 million to help refugees fleeing Islamic State-controlled areas.
Prime Minister Shinzo Abe has vowed a tough response to the Islamic State militants, who in January beheaded two Japanese hostages - a journalist and his companion.
