It could be an opportune moment for a diplomatic breakthrough on Pyongyang's nuclear and missile programs, which have been causing massive headaches for US President Donald Trump.
"They are trying out various options and they have been contradictory on almost every policy that they have tried on or tried out".
South East Asian diplomatic sources told AFP that Tillerson had lobbied U.S. allies to exclude North Korea from the ASEAN regional forum, which meets to discuss Asia-Pacific security issues alongside ASEAN talks. However, the recent Chinese-Russian "double freezing" initiative - suggesting that North Korea stops its ballistic missile and nuclear activities while the United States and its allies halt war games in the region - has been rejected by Washington.
Last week, Kim boasted that North Korea could attack any target in the U.S. after carrying out its latest intercontinental ballistic missile (ICBM) test.
"The way that the message is coming out, it's a bit confusing on the surface of it", said Dr. John Park, the director of the Korea Working Group and a professor at Harvard University's Kennedy School.

"We're not your enemy", Rex Tillerson said, adding that the USA wanted a dialogue at some point.
USA nationals will be barred from traveling to North Korea starting September 1 unless they have a special reason, the State Department confirmed Wednesday. "We would like to sit and have a dialogue about the future".
Thornton confirmed that Washington is seeking to further isolate Pyongyang, but admitted that there had not been time to convince its regional allies to update the guest list before the Manila talks. Speaking last month at an annual security forum in the Aspen, Colorado, CIA Director Mike Pompeo said "it would be a great thing to denuclearize the peninsula, to get those weapons off of that, but the thing that is most risky about it is the character who holds the control over them today".
