LONDON — NATO leaders today warned for the first time about China’s international influence, a seminal step toward aligning the security bloc against the East Asian nation.

“It’s a very big move,” U.S. Ambassador to Nato Kay Bailey Hutchison told the Washington Examiner. “NATO is a defensive alliance. And, it is our job to look at risks of the future, to look at military build-ups, assess any kind of weaponry that is being produced by any other country in the world.”
