Meanwhile, here in Seoul
US Deputy Secretary of State James Steinberg, who arrived in Seoul early Wednesday, began talks with South Korean Foreign Minister Kim Sung-hwan and other high-ranking officials.
The deputy secretary is expected to brief his Seoul counterparts on last week's summit between the US and Chinese presidents, where Beijing, for the first time, expressed concerns over North Korea's uranium enrichment program.
Seoul and Washington are likely to reaffirm their common belief that dialogue between the two Koreas should resume before the six-party talks.
After paying a courtesy call to President Lee Myung-bak and meeting with National Security Adviser Chun Yung-woo, Steinberg will then travel to Tokyo and Beijing to further discuss regional security issues and recent developments on the Korean peninsula.
