Is Russia evading sanctions to repair oil facilities?

There's no doubt the controls on Russian access to technology is impacting its oil industry, but the impact of those restrictions has been frustratingly slow, hence the concerted effort by Ukraine to permanently disable Russia's oil infrastructure. The combination of aerial attacks from Ukraine and limited access to critical spare parts will present Russia with challenges. The spoiler in all of this is the extent to which China can fill the gap left by Western sanctions. Russia has established supply chains with China and built new payment channels, including via cryptocurrencies. The ability of sanctions to strangle Russia's access to technology has been oversold by many political leaders. The reality is that the sanctions created friction, but with the support of China, Russia has been able to maintain its access to the components it needs for 'business as usual' maintenance.”
