North Korean leader Kim Jong Un displayed a new long-range intercontinental ballistic missile at a military parade in Pyongyang that included foreign leaders on Friday. 

The yet-to-be-tested Hwasong-20 was described by the state-owned Korean Central News Agency as having the “most powerful nuclear strategic weapons system.”

The government also displayed shorter-range ballistic, cruise and supersonic missiles at the military parade, which marked 80 years since the founding of the Worker’s Party.

Kim said he hoped to strengthen ties with Russia and work together toward common goals. 

Last summer, Kim’s sister Kim Yo Jong warned the U.S. to not attempt to restart talks centered around denuclearization, adding that Pyongyang would view any attempt to pressure North Korea to denuclearize as “nothing but a mockery.”

“If the U.S. fails to accept the changed reality and persists in the failed past, the DPRK- U.S. meeting will remain as a ‘hope’ of the U.S. side,” Kim Yo Jong said, referring to the nation by its official name, the Democratic People’s Republic of Korea.
