克里與俄羅斯外長將就烏克蘭危機舉行會談
U.S. Secretary of State John Kerry is in London for talks with Russian Foreign Minister Sergei Lavrov on the crisis in Ukraine.
Friday's talks come as the Ukrainian region at the center of the crisis -- Crimea -- prepares for a referendum Sunday that could see it break away from Ukraine and join Russia.
U.S. and European leaders have called the Russia-backed referendum "unconstitutional," and Kerry has warned Moscow of serious consequences if it annexes the Ukrainian peninsula.
But Russian officials say voters in Crimea have a right to self-determination following last month's collapse of the pro-Russian government in Ukraine. And Moscow on Thursday acknowledged deploying thousands more troops and military hardware near the Ukrainian border for maneuvers that will continue for two weeks.
The deployment is in addition to the 20,000 troops Kerry estimates Russia may have in Crimea.美國國務卿克里目前在倫敦，將與俄羅斯外長拉夫羅夫就烏克蘭危機問題舉行會談。
在美俄兩國外交首腦星期五舉行會談之際，作爲危機焦點的克里米亞正準備星期日舉行全民公投，投票結果可能導致克里米亞脫離烏克蘭，加入俄羅斯。
美國和歐盟領導人一直把得到俄羅斯支持的克里米亞全民公投稱做“違憲”。克里警告莫斯科，如果俄羅斯併吞屬於烏克蘭的克里米亞半島，將產生嚴重後果。
但俄羅斯官員表示，在親俄羅斯的烏克蘭政府上月垮臺後，克里米亞選民有權進行自決。星期四，俄羅斯承認向烏克蘭邊境附近增派了數千軍人和軍事裝備，準備進行爲期兩週的軍事演習。
在俄羅斯增派部隊之前，克里估計俄羅斯可能在克里米亞駐軍兩萬
