It’s UN Security Council sanctions. They are not lifting existing sanctions, just not implementing new sanctions on the DPRK.
In Russia, there are two versions about why Russia participated in the sanctioning of DPRK.
First, is that Russia wanted to appease the West so they went along with the sanctions.
Second, is that China wanted the DPRK to stop developing its nuclear weapons (remember the Chinese leadership has a lot of libs who love America at one point, especially before Trump), but the DPRK didn’t listen (good decision, considering what happened to Libya) so China decided to punish DPRK from the UNSC as a warning, and dragging Russia to go along with it.
He's saying here as an answer to "Why Russia is sanctioning DPRK?" basically this:
"Russia wasn't sanctioning DPRK, Security Council was. Sanctions were implemented in completely different enviroment, and, as always, the West did not do anything on their part what we were agreing on. Russia and China were lied to, and the West is suppling weapons to South Korea, SEVERAL YEARS AGO WE AGREED WITH CHINA THAT THERE WILL NO BE NEW SANCTIONS ON DPRK"
By the way, I have limited knowledge of English, and also were writing basic meaning of his words, not literal translation
It's actually more than that, it means that they plan on increasing bilateral trade and economic ties in a massive way such that the old sanctions will become increasingly obsolete as they will simply develop more and more ways of circumventing them.
In effect the sanctions will still be there (because it's virtually impossible to lift Security Council sanctions ever as the West has veto power) but they will be an empty formality. Make no mistake, these developments that we're seeing are HUGE.
OH NO, THEY WERE SITTING IN ROWS, THIS IS FASCIST, EVERYTHING SHOULD BE DISORGANIZED AND THEY SHOULD HAVE TO WORRY ABOUT MASS SHOOTINGS JUST LIKE IN THE UNITED SHITHOLE STATES OF AMERICA!
“We have many interesting projects,” Putin promised, naming as one example the plan to develop Russian railroad connectivity through North Korea. (Source)
Really interested to see if this is pursued.
This is an old article (2018) but it outlines the kinds of projects that have been discussed before concerning Russia-DPRK-ROK:
One such project could be a railway that will be able deliver goods from Russia to South Korea through North Korea. "Once the Trans-Korean Main Line is built, it may be connected to the Trans-Siberian Railway. In this case, it will be possible to deliver goods from South Korea to Europe, which would be economically beneficial not only to South and North Korea but to Russia as well," Moon Jae-in said in an interview with Russian media ahead of his state visit to Moscow.
A gas pipeline coming from Russia to North Korea to be extended to the South is another possibility, he said. "We can also build a gas pipeline via North Korea, so that not only South Korea will receive Russian gas but we will also be able to deliver it to Japan," the South Korean president said.
The project to unite the Korean Peninsula with a gas pipeline has been discussed for a long time, but official talks started in 2011. The negotiations were frozen after relations between Seoul and Pyongyang deteriorated. Last week, Russian energy major Gazprom announced it resumed talks with Seoul over the construction of a gas pipeline connecting Russia with North and South Korea.
The countries could also connect their electricity grids, Moon Jae-in said. "We can also establish a powerline that would allow us to receive electricity from Russia. It could also be delivered not only to South and North Korea but also to Japan.”
Interestingly, DPRK uses two types of rail in their grid. One matches Russian width, the other seems to match Chinese one. So it should make the logistics of the project a bit easier, compared to running rail to Europe (which uses a more narrow rail)
