The move has brought the ROK-run factories to a standstill, threatening a shutdown of the last joint project left between the two neighbors.

In terms of a possible missile test, US officials focused on the limits of Pyongyang's nuclear firepower on Friday, trying to shift attention from the disclosure that Pyongyang might be able to launch a nuclear strike. They insisted that while the unpredictable government might have rudimentary nuclear capabilities, it has not proven it has a weapon that could reach the US.

2. Why is Pyongyang threatening to attack Seoul and Washington?

3. How many DPRK workers did Pyongyang pull from the joint factory park?

Answers:

1. A “cunning ploy”.

3. 50,000.
