South Korean and Chinese defense officials met in Seoul on Friday with North Korea's latest nuclear test high on the agenda.

The director-level talks are held every year, but were completely overshadowed this time around by the North's fourth nuclear test last week, which triggered global condemnation and the promise of fresh UN sanctions.

"The two sides will discuss the security situation on the Korean peninsula, as well as the wider region," a defense ministry official said.

The talks came two days after South Korean President Park Geun-Hye urged China, North Korea's chief diplomatic protector and economic benefactor, to step up to the plate and support genuinely punitive sanctions that would help bring Pyongyang to heel.

"I believe China is aware that if its strong determination is not put into actual, necessary actions, we will not be able to prevent a fifth or sixth nuclear test," Park said.

US Secretary of State John Kerry has also urged China to take a stronger line with North Korea, warning in a call to his Beijing counterpart last week that it can no longer be "business as usual".

North Korea says the January 6 test was of a miniaturized hydrogen.

It was North Korea's fourth nuclear test since 2006, and further evidence of Pyongyang's intention to continue developing its nuclear weapons capability in the face of international censure.
