The global financial turmoil and the standoff over North Korea's nuclear programs will top the agenda when leaders of South Korea, China and Japan meet this weekend, a senior Seoul official said Thursday.

South Korean President Lee Myung-bak, Chinese Premier Wen Jiabao and Japanese Prime Minister Taro Aso are scheduled to hold a summit in the Japanese city of Fukuoka on Saturday.

"The three leaders will focus discussions on financial issues," a senior aide to President Lee told reporters. "Financial cooperation among the three countries will contribute to stabilizing the global financial market."

The official, who spoke on condition of anonymity citing office policy, said the impasse over North Korea's nuclear program will also be a key topic at the upcoming talks.

China also said the financial crisis will be a major agenda item.
