“The DPRK, as a state party to the Biological Weapons Convention (BWC), maintains its consistent stand to oppose development, manufacture, stockpiling, and possession of biological weapons”, North Korea's Institute for American Studies told state news agency KCNA. The Institute said the US claims are groundless and are just excuses for US sanctions against North Korea.

US President Donald Trump said Monday that North Korea is developing chemical and biological weapons which could be delivered by missile.
