North Korea is expected to press China to tone down its economic sanctions when its delegation ­attends an infrastructure and trade summit in Beijing on ­Sunday, observers said.

This undated picture released from North Korea's Korean Central News Agency (KCNA) on May 10, 2017 shows North Korean leader Kim Jong-Un (C) visiting the Rangnang Disabled Soldiers' Essential Plastic Goods Factory in Pyongyang.

Talks between North Korean and Chinese officials on the sidelines of the "Belt and Road Initiative" forum would mainly focus on economic matters, but Beijing was likely to call on Pyongyang to stop its provocations in order for the sanctions to be relaxed, the analysts added.
