Two Things...

 ... in re. this news:

Russian President Vladimir Putin has begun a two-day state visit to North Korea, where he will meet with the country’s leadership for talks on economic, security, and international issues. North Korean leader Kim Jong-un personally greeted Putin at the Pyongyang airport, for the Russian president's first visit since 2000. The trip, which kicked off on Tuesday, will involve a “very busy agenda,” according to Putin’s foreign policy aide, Yuri Ushakov, who noted that the two sides intend to sign several agreements. The Russian president has already authorized the signing of a landmark Comprehensive Strategic Partnership Agreement with North Korea. Ushakov also said Putin and Kim were expected to hold lengthy face-to-face talks to discuss “the most important, the most sensitive issues.” The visit will be largely focused on the international agenda.

The result will highly likely be:

1. A dramatic improvement of North Korea's economic development;

2. North Korea suddenly being able to "develop" state-of-the-are A2/AD capabilities based on North Korea's scientists "breakthroughs" in developing long range supersonic anti-shipping missiles and ISR. Damn, those North Korean scientists. 

Ah, yes, there is a third point--it is all on the border with South Korea which houses some US military bases. Nothing that intermediate range missiles with excellent targeting cannot rectify.
