evidence: The location of "Heglig" (which Southerners have long referred to as Panthou) has yet to be negotiated vis-à-vis the "1 January 1956 border," the determining point of reference in establishing whether a wide range of locations lie in the South or the North. Although the Comprehensive Peace Agreement (CPA) repeatedly and explicitly stipulates the "1 January 1956 border," the precise location was to have been to be a matter that required extensive research and negotiation by the Technical Boundary Committee (TBC). [...] In short, the location of Heglig remains to be negotiated, even as Khartoum refuses to negotiate—and the regime is distinctly less likely to do so now that its pre-emptive geographic claim of the region has been ratified by a series of statements by international actors of consequence. Given Juba’s determination that Heglig will not be allowed to become a future staging ground for additional assaults on Southern territory, and the strong belief by many Southerners that Heglig is south of the "1 January 1956 boundary," either the geographic status of Heglig is negotiated, or there will be no peace. [...] • "The move by the South Sudanese armed forces to occupy Heglig in Sudan is completely unacceptable," declared the UK’s Minister for Africa, Henry Bellingham.
