The techniques are similar. As I mentioned before, it's known that Venezuela and Russia have been co-operating in information operations for 20 years, since they funded Telesur in Venezuela and Russia Today. That co-operation has been ongoing for two decades in the way they design information manipulation targeting different populations both inside their countries and internationally.
They share tactics. They share techniques. They use similar ways to deploy propaganda and information manipulation, but that doesn't mean they work together on the operational side. Venezuela had its own apparatus for deploying propaganda, its own trolls, its own troops, its own bots and its own...all the same apparatus similar to Russia but separate. They coordinate in some campaigns, particularly those targeting international audiences in issues related to human rights and issues related to sanctions. In those cases, they work together, but when they are targeting their domestic audiences, they work separately. Each of them has a different apparatus, with similar tactics but not operationally linked.
