Abstract:From February 1951 to June 1951, UK changed her stance from approval of altering Chinas right of representation in the UN to the support of suspending the discussion of this issue. Beside the special relation between U.S.A and the UK, the change of Uks stance lies in that the situation for voting in the UN was unfavorable for the new China. As the Chinese Peoples Volunteer Army got involved into the Korean War, the member countries of the UN, including UK, feared the war would expand, and they started to doubt whether the new China would follow the cooperative spirit of the UN Chart and mutually preserve the peace. In addition, it was doubted whether the new Chinas access to the UN would add the political weight of the Soviet Union on the international stage. After having analyzed the situation for voting, UK believed that it was not the good time for the new China to strive for her right of representation in the UN, thus UK voted for postponing the above discussions in the UN agencies.
