Russia's permanent representative to international organizations based in Vienna said Wednesday that the experience of Iran's nuclear deal 2015 has proved to North Korea that the US is not reliable.

Iran Press/Europe: Mikhail Ulyanov on Twitter pointed to the fate of the Iranian nuclear deal 2015 known as the Joint Comprehensive Plan of Action (JCPOA) and the US withdrawal from it, adding that the US policy on the JCPOA has caused North Korea to distrust the United States.

Many countries believe that US behavior toward the Iran nuclear deal has undermined the confidence of the international community in Washington, including the possibility of an agreement between Washington and Pyongyang on nuclear issues.

North Korean leader Kim Jong Un said Wednesday there was no reason for his country to suspend missile tests.

"If the United States continues its hostile policy against North Korea, there will never be nuclear disarmament on the Korean Peninsula," said Kim Jong Un.
