Russia is evading sanctions through a network of companies affiliated to Coral Energy, a commodities trader.
Coral Energy's illicit trading and financing has been backed by several European financial institutions and oil companies.
This scheme reveals the flaws in the western-implemented sanction system.
The EU must take responsibility for allowing Greece to sell oil tankers to Russia.
Sanctions are hardly respected due to the lack of a single administration in the EU.
Sanctions become less effective due to the hypocrisy of banks and oil companies doing business with shady companies.
Responsibility also lies with the states allowing oil trade without transparency.
Conclusion: The current sanctions are ineffective in handling aggressive actions from Russia. There is a need to review and strengthen the enforcement of sanctions, requiring greater transparency and coherence from states and financial institutions in their execution.
