This could be a double edged sword:
The United Nations Security Council on Wednesday unanimously adopted a resolution that dramatically expands existing U.N. sanctions on North Korea in response to its Jan. 6 nuclear test, a measure largely negotiated by Washington and Beijing.U.S. Ambassador Samantha Power said the new sanctions on Pyongyang go further than any U.N. sanctions regime in two decades and are aimed at cutting off funds for its nuclear and other banned weapons programs.Under the sanctions, all cargo going to and from North Korea must be inspected and North Korean trade representatives in Syria, Iran and Vietnam are among 16 individuals added to a U.N. blacklist, along with 12 North Korean entities.Previously states only had to inspect North Korean cargo shipments if they had reasonable grounds to believe they contained illicit goods. – Source: U.N. imposes harsh new sanctions on North Korea drafted by U.S., China | Reuters
The reason why I say that this could be a double edged sword is that Kim Jong-un has been known, much like his Father; to be an unstable leader. This could lead to more rockets being fired into South Korea. Which could lead to South Korea going to war, which they have said that they would be willing to do. Park Geun-hye has stated that she will defend her Country if needed. If you read her bio, you will fully understand why. To say, that she personally has been affected by North Korea’s lunacy, would be an understatement.
So, I would say, that it would be a good idea to keep an eye on that little situation.
