(Despite North Korea's fickle behavior and attitude )
U.S. Secretary of State John Kerry says Washington's diplomatic engagement with Beijing over the North Korean nuclear issue has kept Pyongyang (quote-unquote) "quieter" in recent months.
Appearing on NBC's Meet the Press Sunday, Kerry said cooperation with China since his visit to that country last year hasn't led to the expected goals in regards to Pyongyang's denuclearization, but that they were moving forward in that respect.
Kerry's remarks likely reflect the fact the North didn't conduct a fourth nuclear test as it had threatened to earlier this year, and that it hasn't launched any LONG-range missiles as of late.
The UN Security Council last week, however, condemned Pyongyang's recent series of short-range missile tests towards the East Sea off the Korean peninsula.
