question:
Beijing (CNN) China -- North Korea's only global ally and biggest trading partner -- has put on a stoic face since Pyongyang successfully conducted its sixth nuclear test Sunday. President Xi Jinping didn't mention his country's unruly neighbor at all in his closing address at the BRICS summit of emerging economies Tuesday, or in earlier speeches, although a communique issued by the group expressed deep concern and called for the crisis to be settled peacefully. But the test of a hydrogen bomb couldn't have sat well with China's leader. It's the third time in one year that North Korea has overshadowed a major Chinese event -- previous missile tests coincided with the unveiling of Xi's global economic blueprint at his Belt and Road summit in May and the G20, which China hosted last September.Voices in China diverging from official line on North Korea policyNuclear test seen as an embarrassment to Xi JinpingXi makes no reference to North Korea in closing summit speech 
 Question:"But if it hopes to see _ resolve the issue, it simply won't work," he added.
