It most definitely has to do with cv.
The Saudi and Russian spat is because of the drop in oil, which is caused by China shutting its economy down and the assumption there will be other slowdowns/disruptions and thus a low demand for oil.
Falling prices started this and the prices started falling because of cv.
The drop in oil prices is b/c Saudi Arabia is threatening to flood the world's oil supply, thus putting the Russian oil producers in jeopardy. It is also squeezing small American oil producers and fracking operations. If a drop in demand in China b/c of the virus was causing the drop in price, the Saudis would accomplish nothing by flooding the market. This is all a power play by the Saudis to punish Russia having failed to reach an agreement at OPEC+.
