Joshua Cooper Ramo, the commentator who offended residents during coverage of the Pyeongchang Olympics opening ceremony by straying into the sensitive issue of Japanese-Korean relations, has been taken off the air, U.S. broadcaster NBC said Monday.

"Joshua Cooper Ramo has completed his responsibilities for NBC in Pyeongchang, and will have no further role on our air," an NBC spokesman said.

NBC, a unit of Comcast Corp., had announced in December that Ramo would be a contributor at the games, having previously served as an expert on culture and geopolitical issues during the 2008 Beijing Olympics.
