U.S. report: North Korea could use bioweapons

The United States believes that North Korea could someday use biological weapons, which could pose additional security threats on top of the country's drive for nuclear weapons, according to a U.S. government report.

The annual report on international agreements and commitments to arms control, disarmament and non-proliferation said that North Korea is continuing to develop biological weapons and has not reported any developments to the Biological Weapons Convention. North Korea became a BWC state party in 1987, Yonhap News reports.

"The United States judges that North Korea may still consider the use of biological weapons as an option," the U.S. State Department said, according to Yonhap News. "North Korea continues to develop its biological research and development capabilities, but has yet to declare any relevant developments as part of the BWC confidence-building measures."

According to the report, North Korea continues to develop its nuclear capability with uranium enrichment activities and the construction of a light-water reactor. The country continues to develop these nuclear areas despite a commitment to U.N. Security Council resolutions signed in 2005 with nuclear negotiation partners Japan, Russia, China, South Korea and the U.S, according to Yonhap News.

The report is similar to the tone of last year's North Korean report. One key difference is that the U.S. is less concerned of North Korea's suspected nuclear ties with Myanmar, also known as Burma.

"Concerns that the United States expressed in last year's compliance report regarding Burma's interest in pursuing a nuclear program, including the possibility of cooperation with North Korea, were partially allayed," the report said, according to Yonhap News.
