In july 1999, the former President Lee of R.O.C. made a response to questions submitted by the reporter of Deutsche Welle radio station from German. Lee brought up an idea that the cross-strait relationship is "as a state-to-state relationship or at least a special state-to-state relationship." Thus, the statement caused different reflection from internal and international. The statement of "a special state-to-state relationship" that represents in sovereignty and the statehood between the cross-strait relationship abandons the "one China" principle that R.C.C.insisted in the past but differs from the view of P.R.C.. Certainly, P.R.C. criticized such kind of statement that violates "one China" principle and blocks the process of the national unification.Soon, P.R.C. unilaterally declared the fundation of the exchange and the discussion not existed any more. After a series of verbally disparaged and militarily intimidated from P.R.C. and not supported from U.S.A. government, R.O.C. has obviously shrunken back in the statement of "a special state-to-state relationship".Even after the D.D.P. which was definded independential party won the president campain of 2000, the president elect Cheng didn't show out his view of suportting "a special state-to-state relationship" and amending constitution and as soon as possible that brought up before the president campain. Therefor, in the process after bringing up "a special state-to-state relationship", it show out an epitome of the sovereignty conflict between the cross-strait. In fact, the statement of sovereignty that the R.O.C government declared from 1949 had been suppressed by P.R.C.. In the international politics, it bulges out the difficult position of R.O.C.'s sovereignty. The thesis, "the sovereignty between R.O.C. and P.R.C.", investigates the sovereignty issue between the cross-strait from 1949 to 2000. It founds on an approach of international politics and international law. Though sovereignty is the issue of international law. But the thesis supposes an idea that the sovereignty issue between the cross-strait is an political issue more than a legal. The thesis would prove this view by describing the international political events and bringing up a series of international contracts, official proclamation of the sovereignty issue between the cross-strait from 1949.So, the conclusion of the thesis would bring up a point, that is the difficult position of R.O.C.'s sovereignty.
