North Korean leader Kim Jong-un may visit Indonesia in his first overseas trip since ascending to power in the reclusive nation.

Reports suggest Kim could attend the Asian-African conference in Indonesia which is set to take place in April.

"For Kim Jong-un ... the Bandung [Indonesian city] meeting will be a noteworthy diplomatic schedule," a South Korean government source told Yonhap news agency.

The summit is scheduled to take place in Jakarta on 22 and 23 April and will be followed by a meeting on 24 April in Bandung.

Kim's grandfather and the founder of North Korea, Kim Il-Sung, attended the conference in 1965 to mark its 10<sup>th anniversary.

Kim, who is thought to be in his 30s, has not travelled abroad since 2011, the year he took over the regime. The reticent North Korean leaders usually visit China, a close ally of North Korea, for their inaugural foreign trip.

Nevertheless, earlier reports had also suggested that Kim would visit Russia in May this year to commemorate the 70<sup>th anniversary of its World War II victory.
