North Korea is likely to conduct one or more nuclear test to miniaturize warheads that could be attached to missiles, a Chinese expert warns.
Li Bin, a professor of Tsinghua University, told a conference hosted by the Asan Institute for Policy Studies in Seoul on Wednesday, "North Korea conducted its first nuclear test with a relatively small nuclear weapon but failed to achieve a normal explosive yield. It must have made the weapons bigger to increase their explosive yield in its second and third nuclear tests."
"The North will therefore probably conduct at least one more nuclear test to miniaturize the weapon."
The North has claimed that it succeeded in making nuclear weapons smaller and lighter with its third nuclear test, but Li said that is implausible.
"The North doesn't have the technology to fit a nuclear warhead on an intercontinental ballistic missile," he added.
Chu Shulong, another professor from Tsinghua University, said six-party nuclear disarmament talks do not make any sense unless the North takes action to abandon its nuclear and missile programs first.
"There is a likelihood that the North will carry out another provocation similar to the one it launched early this year," Chu added.
He urged South Korea, the U.S., China, and Russia to work out a military response if that happens.
