Six years after inheriting power from his father, Kim Jong Un has established his authority domestically, taken North Korea to unprecedented nuclear heights and is now looking to flex his muscles abroad. Kims shock visit to Beijing traditionally Pyongyangs strongest backer, although the relationship has soured during his time in power is the first time he is known to have set foot outside the impoverished North since he assumed the leadership. But Kim, who is in his mid-thirties, has repeatedly shown an ability to stamp an outsized footprint on the global stage without ever leaving home. The third member of the Kim dynasty to rule the North, he has turned his country into a bona fide nuclear power with intercontinental ballistic missiles he says can reach across the globe, including the United States with state media regularly picturing him overseeing launches. And he secured a major diplomatic breakthrough for his ostracised regime earlier this month when US President Donald Trump said he would be willing to hold summit talks with the young leader.
