Can dividend payments of russian stocks be disrupted if (financial) sanctions are placed against russia?

Hello fellow traders and investors,

After the steep 30 % drop of russian stocks today, many price alerts got triggered and I am very tempted to build up a russian position for diversification. Most of it will be commodities which are soaring in price while the stock prices got hammered down (due to the swelling russia-ukraine war probably). I know that sanctions (the EU announced they will also place some) will hurt commodity export, but thats not my concern rn. There are also plans to place sanctions on the financial sector of russia, freezing assets etc. Could / will this disrupt, delay or even prevent the payment of dividend? There are also some VIE / ADR structures like for Gazprom – will this make a difference?

Thanks in advance for your knowledge.
