North Korea and Russia have begun building their first road link, which will further the bilateral relations between the two countries, amid Pyongyang's continued support for Moscow in their war in Ukraine.

The two countries have vowed to expand bilateral relations after North Korea sent troops and weapons in support of Russia’s war against Ukraine.

The construction marks the first ever bridge for cars and motor vehicles crossing between Russia and North Korea and is a “significant milestone” in the relationship between Moscow and Pyongyang, Russian prime minister Mikhail Mishustin said on Wednesday as he attended the groundbreaking ceremony in a video conference.
