Trump nominee talks tough on China, Beijing reacts

At this week's Senate confirmation hearings, Donald Trump's choice for Secretary of State, Rex Tillerson, had harsh words for China's island-building in the South China Sea. China's state-run media have called that a threat that might require retaliation. Chinese officials have responded differently.

David Wertime, senior editor at Foreign Policy magazine, says there is often a great gap between political speech and government policy.
