"They have extended the range now out to a point that it is hard to credibly argue that North Korea couldn't have the USA eastern seaboard within its range", Vipin Narang, associate professor of political science at MIT, told the BBC.
"I think the Chinese are doing a lot", Tillerson told reporters when asked if he shares the president's sentiment.
In September, Lavrov explained, the American colleagues hinted that the next exercises are only expected in the spring, Pyongyang can take a pause and also "not to make any sudden movements", and why in this situation not to try to establish a dialogue. North Korea has been buying oil from Russian Federation as well but in much smaller amounts and continues to be dependent on Chinese supplies.

"The latest U.S. action seemed to be directed towards provoking Pyongyang into taking some rash action", he told journalists on Thursday.
China could control North Korea's regime but doesn't see the need to do so - at least not yet, says a US senator. North Korea's leader Kim Jong-Un said this test showed that North Korea had become a full nuclear power.
Mr Lavrov said the way the USA was handling the situation was dangerously provocative.
What worsens that situation, Wicker went on to say, is that China remains an adversary of the United States and its allies because it wants to dominate the Pacific Ocean.
North Korea often justifies its development of nuclear weapons as a measure aimed at countering alleged American aggression.
