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

North Korea said the construction of a new bridge linking it to Russia is a "significant" development of relations between the two countries, state media KCNA reported on Thursday.

Russia’s growing technological assistance has the potential to bolster North Korea’s development of ICBMs and SLBMs, nuclear-powered submarines, and low yield nuclear weapons.
