North Korea has expressed displeasure over South going ahead with joint military drills with the US forces which are held every year in spring and summer.

Axar.az reports citing Anadolu Agency that Kim Yo Jong, sister of North Korean leader Kim Jong-un stated this.

“I view this as an undesirable prelude which seriously undermines the will of the top leaders of the North and the South wishing to see a step taken toward restoring mutual trust and which further beclouds the way ahead of the North-South relations" - she stated.

Kim Yo Jong works as vice department director of the Central Committee of the Workers' Party of Korea.

However, Seoul said it is "still discussing with the US side the joint military exercises" set for later this month.

“Drills will be a joint decision between South Korea and the US,” South Korean Defense Ministry Spokesperson Boo Seung-chan said, according to the daily Korean Herald.
