North Korea is as likely to clash with China about its use of the Bohai as Great Britain is likely to clash with USA about its use of the Atlantic.
That said, a nuclear but unstable NK isn't good for anyone in the world. As long as NK is more about the Kim family than about the rule of the people for the people, there is no real way to help them that wouldn't backfire further down the road.
Honestly I think Kim Jong Un has been a vast improvement over his father at putting the people first (or at least bumping them up in the priority list) so things are going well.
When NK is ready, China can provide stable institutions and shield them. But when they are OK with leaving behind their personality cult and embracing modern socialism is a decision that can only be left to the North Korean people, its not one that China can force them to make.
