Seoul, South Korea (CNN) - North Korea's nuclear program and a free trade agreement will be front and center on President Obama's agenda as he visits South Korea - the last leg of his trip to Asia.
Obama landed in South Korea on Wednesday evening local time. He will visit the U.S. Embassy in the capital, Seoul, and meet with President Lee Myung-bak on Thursday.
The two leaders will have a bilateral meeting and then hold a news conference. They later will have a working lunch. Before Obama leaves Thursday, he'll visit troops at a U.S. Air Force base.
The nuclear program of North Korea - South Korea's neighbor to the north - has been a major concern for the United States and many Asian powers.
