Ukraine has won a seat on the U.N. Security Council, giving the country a new platform to spar diplomatically with permanent member Russia. Four other countries — Egypt, Japan, Senegal and Uruguay — were also elected to the council. All five countries were unopposed in their bids for the non-permanent seats. In addition to possible fireworks between Ukraine and Russia, there could be clashes between Japan and rival China, also a permanent member, as well as with Russia. Japan has territorial disputes with both countries.
