In the aftermath of the controversial 2006 North Korean nuclear test, Foreign Ministry Spokesman Le Dzung expressed the Vietnamese Government's grave concern over the test, stating that it will heighten tensions and threaten the region's stability, and stated that Vietnam supports the "denuclearization" of the Korean peninsula. After the ROKS Cheonan sinking of 2010, Foreign Ministry Spokeswoman Nguyen Phuong Nga said: "The sinking of Cheonan is a regrettable incident. The Government of Vietnam expresses its heart-felt condolences to the Government of the Republic of Korea for the loss of lives in the sinking. Vietnam has attentively and closely been following the current developments in the Korean Peninsula. Vietnam consistently and persistently supports peace, stability in the Korean Peninsula, and favors dialogue for peaceful settlement of all matters. Vietnam wishes that parties concerned could exercise restraint for the sake of peace, stability in the Korean Peninsula and in the region."
