BEIJING (Reuters) - China said on Tuesday it strongly opposed North Korea's latest nuclear test and urged its ally to abide by its non-nuclear commitment and not take any actions that would worsen the situation on the Korean peninsula.

"It is China's firm stance to realise non-nuclearisation for the Korean peninsula and prevent nuclear proliferation and maintain peace and stability in northeast Asia" the Foreign Ministry said in a statement.

North Korea, which is banned under U.N. Security Council resolutions from developing nuclear and missile technology, said the test "was carried out at a high level in a safe and perfect manner", according to its official KCNA news agency.
