Facing military exercises, sanctions and confrontation, the DPRK would go its own way, a choice for self-protection, Liu said.
He said China has called for denuclearization of the Korean Peninsula and a solution to the issue through the six-party talks and dialogue within the framework of the United Nations.
Although the policy has not resolved the issue so far, it at least does not intensify the dispute, Liu said.
Ruan, from the CIIS, expressed the hope that all parties concerned would resume diplomatic contact after a period of time.
"In the future, distrust and antagonism between the United States and the DPRK should be resolved by mechanisms of multilateral dialogue like the six-party talks," he said.
"The Chinese side should continue to play the role of a peacemaker and mediator," Ruan said. "After all, only negotiations could resolve the issue fundamentally."
