Respected Your Excellency Kim Jong Un,

I express thanks for your congratulations on my election as president of the Russian Federation.

I, like you, have a willingness to boost the friendly and cooperative relations between our two countries and implement as ever the already reached bilateral agreements.

I am convinced that this is in full line with the interests of our two peoples and will contribute to ensuring the peace and security on the Korean Peninsula.

I wish you and the people of the DPRK happiness, wellbeing and successes.

Sincerely yours.
