Chinese Foreign Minister Wang Yi on Wednesday urged North Korea to stop its testing of missiles and nuclear weapons, warning of the possibility of a "head-on collision" by the two Koreas as tensions rise. Wang said South Korea and the US should reciprocate for such a step by halting the joint military exercises that they hold each year. Such a "dual suspension" could facilitate the restarting of negotiations between the parties, the minister said, adding "Holding nuclear weapons won't bring security, using military force won't be a way out."
