This post is exagerated. But yes Russia blocked imports of Chinese trucks to save market share for KAMAZ and Ural. A lot of this is because the market is saturated at a time interest rates are still high and demand is low. Russian truck makers can easily cover existing demand by themselves.
You can expect truck imports to be allowed back eventually but there will be some kind of barrier to safeguard local truck makers.
As for GLONASS that person has no idea what they are talking about. All vehicles in Russia with no exception must have the ERA-GLONASS system. This is not a navigation aid. It is a system where in an emergency it communicates with Russian emergency services requesting them to assist you. Russia is pretty sparse, you might be hundreds of km from someone else when your car breaks down or worse. So this is mandatory.
