专家：美国应施压朝鲜披露所有秘密核设施

Washington must press Pyongyang to reveal the existence of secret nuclear sites, including the second uranium enrichment facility known as Kangsong, in any nuclear disarmament deal, said a former United Nations nuclear inspector.

The United States must “make sure [North Korean officials] include these additional sites upfront into the deal,” said David Albright, a former United Nations nuclear inspector and current nuclear proliferation analyst at the Institute for Science and International Security. ((ACT 6))

Albright made his comments as another expert said North Korea's increased nuclear activities since the summit in June have raised concerns whether it has violated the agreement made with the U.S. to denuclearize the Korean Peninsula.

Before U.S. Secretary of State Mike Pompeo headed to Pyongyang on Thursday to discuss denuclearization details, reports of North Korea's secret nuclear sites and upgrades to the Yongbyon nuclear site surfaced. The reports fueled speculation about the real intentions of North Korean leader Kim Jong Un regarding denuclearization, despite what was said to U.S. President Donald Trump during last month's summit in Singapore.

NBC and The Washington Post reported last week that U.S. officials believe, based on the latest intelligence assessments, that North Korea has been making preparations to deceive Washington about how many weapons it has in its possession and that the Kim regime has been increasing its production of enriched uranium for nuclear weapons at several secret sites since the summit.

Aside from the Yongbyon facility, which is the only nuclear site the North acknowledges, Pyongyang also operated Kangsong, a secret underground facility that is believed to have the capability to enrich twice the amount of uraniumuranium than Yongbyon.
