The powerful sister of North Korean leader Kim Jong-un on Tuesday warned of "renewing" the country's records in strategic deterrence, denouncing the recent arrival of a U.S. aircraft carrier in South Korea as an attempt to "threaten and pressurize" its regime.

The U.S. aircraft carrier USS Carl Vinson arrived at the southern port city of Busan in South Korea on Sunday as a show of force against North Korea, South Korea's navy said.

The Carl Vinson is the first U.S. carrier to visit Busan since the USS Theodore Roosevelt docked there on June 24. Days later, the Theodore Roosevelt and its strike group took part in Freedom Edge, the first major trilateral maritime and aerial exercise involving the United States, South Korea and Japan.
