Russia’s foreign minister has warned the U.S., South Korea and Japan against forming a security partnership targeting North Korea.

North Korea is set to treble the number of its troops fighting for Russia along the front lines with Ukraine, sending an additional 25,000 to 30,000 soldiers to assist Moscow, according to an intelligence assessment from Ukrainian officials.

It was reported last week that North Korea plans to triple the number of troops fighting with Russia along the front lines in Ukraine—sending an additional 25,000-30,000 troops. Troops will arrive in the next few months, adding to the 11,000 North Korean troops that were sent in November.

The United States, Japan, and South Korea are strengthening their military presence in the Korean Peninsula in response to North Korea's nuclear program.

SEOUL (Reuters) -Russian Foreign Minister Sergei Lavrov arrived in North Korea on Friday, North Korea's state media KCNA said on Saturday, the latest visit by a senior Russian official to the isolated state amid warming ties between the countries.

North Korea is set to ship off 30,000 more troops to help Russia’s invasion of Ukraine, tripling the number of soldiers it has given Moscow.

Relations between Russia and North Korea have flourished in recent years, with North Korea supplying troops and ammunition to support Russia's war against Ukraine in return for military and economic assistance.

Russia and North Korea are meeting for a three-day visit that is already sending other countries into a tailspin, as World War 3 fears mount.
