Chinese President Hu Jintao and South Korean President Lee Myung Bak on Monday held talks that focused on North Korea's new leadership and efforts to persuade Pyongyang to abandon its nuclear weapons programme, dpa reported. The two presidents held an "in-depth discussion" on the Korean Peninsula and pledged to "work together for the sake of peace and stability," Yonhap news agency quoted an unnamed South Korean official as saying. Chinese state media said Lee praised China's efforts to promote the denuclearization of the Korean Peninsula and urged it to “continue to play a positive role in this respect. " Hu said China supported more talks between North Korea and South Korea. China was "willing to enhance communication and coordination withall relevant parties" to strengthen the security of the Korean Peninsula, Hu was quoted as saying. Monday's talks followed last month's death of North Korean leader Kim Jong Il.
