The move of the Vinson strike group is in response to recent North Korean provocations, the official said, according to CNN.

Adm. Harry Harris, the commander of U.S. Pacific Command, directed the USS Carl Vinson strike group to sail north to the Western Pacific after departing Singapore on Saturday, Pacific Command announced.

It is not uncommon for aircraft carriers to operate in that area, and the United States regularly deploys military assets, such as aircraft, to the region as a show of force. In fact, the Vinson was in South Korea last month for military exercises.
