The security environment in East Asia in 2020 is set to hinge on whether tensions between North Korea and the United States will escalate, as leader Kim Jong Un has accused Washington of missing a deadline set by Pyongyang for nuclear talks.

Concern is growing that Pyongyang will resume nuclear or intercontinental ballistic missile tests to compel U.S. President Donald Trump to lift economic sanctions as he is eager to secure diplomatic achievements ahead of the presidential race in November.

Some observers, however, said Kim, whose primary goal is to ensure the continuation of the monolithic political system led by him, may refrain from actions that would pose direct threat to Washington, given that the risk of military conflict would increase.
