U.S. Vice President Joe Biden on Thursday sidestepped a question about his presidential ambition with a joke that he’ll give an answer in the Korean language.

Biden, who has been noncommittal about whether he’ll run for president, was asked the question by a pool reporter while waiting for South Korean President Park Geun-hye to arrive at his residence for a lunch meeting.

“Mr. Vice President, Are you running for president?” a pool reporter asked.

“I’ll answer in Korean,” Biden responded.

As the reporter kept asking similar questions, Biden said, “I’m here to greet President Park. I’ll talk to you all about that later.”

As Park’s motorcade arrived, Biden greeted her, saying “Madame President, welcome to my home. It’s so nice to see you, and look at the weather you brought,” gesturing to the cloudless sky on a sun-soaked day tinged with a slight chill, according to the pool report.

Park is the first Asian leader to be invited to the vice president’s residence at the Naval Observatory.
