Senior U.S. diplomat says U.S., China can still cooperate on North Korea

A senior U.S. diplomat said on Wednesday that the United States and China can still work together against North Korea's development of weapons of mass destruction, despite tensions between Washington and Beijing."While there is much more China could do to enforce binding sanctions and prevent sanctions evasion – and we will continue to engage the Chinese on that issue," the number two diplomat at the State Department told the Senate Foreign Relations Committee.
