A video has gone viral where Russian President Vladimir Putin could be seen driving a Russia-built Aurus limousine with North Korean leader Kim Jong Un sitting beside him.

In the video, Putin could be seen behind the driving wheel in the vehicle which is the official presidential car in Russia.

The two leaders can be seen in the video chatting and laughing while riding the vehicle.

Meanwhile, the US has expressed concern over Putin's suggestion that Russia could supply weapons to North Korea.

Matthew Miller, a US state department spokesperson,  said:"  You recall that we first made public that the DPRK was providing Russia with military equipment that would show up on the battlefield in Ukraine, has showed up on the battlefield in Ukraine. We’ve seen them provide thousands of artillery shells and other munitions that they have been using to shell Ukrainian cities, Ukrainian villages, and kill Ukrainian civilians."

" We have been taking this quite seriously. And I will say it’s one of the reasons why we have been prioritizing strengthening our ties with allies and partners in the Indo-Pacific throughout this administration, including through the historic trilateral agreement we had with the Republic of Korea and Japan, through AUKUS, through other work because of the potential for deepening cooperation between these two countries," he said.

He said, " So it continues to be a problem, and we’re going to work on it with our allies and partners, including those in the region."

Meanwhile, South Korea has also expressed concern over  Moscow signing a new treaty with Pyongyang on providing each other military assistance in case of an armed attack on either of them.

According to reports, South Korea urged Russia on Friday to "immediately halt" military cooperation with North Korea and "act responsibly".

First Vice Foreign Minister Kim Hong-kyun delivered the position to Russian Ambassador Georgy Zinoviev as the foreign ministry called in the top Russian envoy to lodge a protest over the treaty inked between Moscow and Pyongyang at their leaders' summit Wednesday, reported Yonhap news agency.
