South Korean Defence Minister Shin Won-sik visited a nuclear-powered aircraft carrier, the USS Carl Vinson on Wednesday.
Shin was welcomed by Rear Admiral Carlos Sardiello, commander of Carrier Strike Group "The US-ROK alliance remains at a high level of readiness to protect the Republic of Korea against any threat, any adversary," said Sardiello in his welcome speech.
