WASHINGTON (AP) - President Barack Obama is urging China's president to send North Korea a message that "its provocations are unacceptable."
Obama called Chinese President Hu Jintao on Sunday night to discuss North Korea, the White House says. The leaders talked about their common interest in peace and stability in Asia and the importance of keeping the Korean peninsula free of nuclear weapons.
The White House says Obama and Hu agreed to work together toward those goals.
Obama condemned North Korea's pursuit of a uranium enrichment program as well as its shelling of a South Korean island last month.
And he stressed the need for the U.S., China and Europe to work together to address Iran's nuclear program.
