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

Clinton, Iowa (CNN) The final days before the first-in-the-nation caucuses are agonizing for many Iowa evangelicals as they waver between Ted Cruz and Donald Trump. At events for both GOP presidential candidates across the Hawkeye state, voters say they are torn between backing the committed Christian conservative who is solid on their principles, or the once-liberal, thrice-married candidate who they believe would make the stronger president. Sherry Benson, a 57-year-old graphic designer from Marshalltown, said she is still trying to come to terms with Trump's evolution on abortion. Benson calls abortion "the biggest sin of our country." The anti-Trump television ads detailing his shifts—with arresting clips of the candidate talking about his support for abortion in 1999—have kept that issue fresh on her mind.Evangelicals are among the most reliable caucus-goers every four yearsThey're torn between choosing Donald Trump, Ted Cruz
