奥巴马在白宫会晤乌克兰新总理

U.S. President Barack Obama is hosting Ukraine\'s interim prime minister at the White House Wednesday, as the standoff between Russia and the West over the Ukrainian region of Crimea continues.

This is President Obama\'s first meeting with Prime Minister Arseniy Yatsenyuk and is meant to underscore U.S. support for the new government and the Ukrainian people.

As part of the talks, Mr. Yatsenyuk and President Obama will discuss financial assistance for Ukraine. The U.S. has already pledged $1 billion in aid.

The Ukrainian prime minister\'s visit to Washington comes as Crimea, with its majority-Russian population, prepares for a Moscow-backed referendum Sunday on joining Russia.

European Commission President Jose Manuel Barroso says the Group of Seven most developed economies will call on Russia Wednesday to stop all efforts to "annex" Crimea. The G7 includes Britain, Canada, France, Germany, Italy, Japan and the United States.

这是奥巴马总统首次与亚采纽克会面，奥巴马希望通过会晤来强调美国对乌克兰新政府和乌克兰人民的支持。

俄罗斯族人占多数的克里米亚定于星期天就克罗米亚是否加入俄罗斯问题举行全民公决。这次公投得到俄罗斯的支持。

白宫说，奥巴马总统和亚采纽克临时总理将讨论经济援助议题。美国已保证向乌克兰提供10亿美元的援助。

欧盟委员会主席巴罗佐说，工业化七国集团星期三将要求俄罗斯停止“吞并”克里米亚的一切努力。七国集团的成员国有英国、加拿大、法国、德国、意大利、日本和美国。
