I believe Xi, the smart guy.

First summit talk with President Park Geun-hye and Xi jinping is set for June 27. With this meeting, President Park plans to enlist Beijing's help in pressuring Norh Korea to give up its nuclear programs.

As a key provider of economic aid and diplomatic protection for North Korea, China has long been considered the only country with any meaningful influence over Pyongyang, though it has been reluctant to use that leverage over concern that pushing the North too hard could hurt its national interests.
In recent months, however, China has apparently been taking a tougher approach to Pyonyang especially after the North's long-range rocket launch in December and its third nuclear test in February. Also, in the first summit with U.S. President Obama, Xi Jingping showed a strong agreement on the North Korean nuclear issue. Both leaders delivered a stern message to Pyongyang by declaring that they would not accept the North's posession of nuclear weapons.

The summit between Park and Xi should be the opportunity to further bolster cooperation in making Pyongyang realize that its bad behavior will never be rewarded and it has no other choice but to change course and become a responsible member of the international community.

Xi Jingping, as a very smart guym remembers his statements on the talk with Obama, and will force Pyongyang to give up its nuclear ambitions and closely cooperate with Korea to achive denuclearization of North Korea. He definitely knows what's right and it's time to gether up the North's reins.
