Mr.Nill:Hi，Captain Li！So great to meet you on this party！
Cpt.Li:Me too，Mr.Nill.
Mr.Nill:It seems that today’s occasion draws a lot of attention，doesn’t it？
Cpt.Li:Yes.It is the 70th anniversary of UN Day.
Mr.Nill:Nobody has expected that an organization set up on Oct.25 1945 comes all the way up now and is still getting stronger.
Cpt.Li:After World War II，it is UN that is striving to maintain international peace and security，develop friendly relations among nations，promote social progress，and improve living standards and human rights.
Mr.Nill:Yes.No other document like the UN Charter has been exerting so profound influence over world peace and development.
Cpt.Li:Have you heard of that the Secretary General is proposing a new peacekeeping mission in Syria？
Mr.Nill:Only some hearsay.It takes a long time between the UN，the TCCs and the host country to negotiate all matters about sending troops there.
Cpt.Li:You are quite right.The Security Council has the final say.All the five permant members have the veto power.
