Russia's insistence on paying for Russian gas in rubles has rattled European countries: Greece held an emergency meeting of suppliers, the Dutch government would urge consumers to use less gas, and the French energy regulator told consumers not to panic. Russian gas meets one-third of Europe's annual energy needs.

Russia said they could expand their demand for ruble payments for other commodities, including oil, grain, fertilizer, coal, and metals, which raised the risk of recession in Europe and the US. 

Moscow is expected to unveil its ruble payment plan in early April, but it said it would not immediately ask buyers to pay for gas in rubles.  

Western countries have said paying in rubles would be a breach of contract, and renegotiation could take months or longer. This uncertainty has pushed commodity market prices higher.

The supply and prices of other commodities like the Praseodymium Oxide suppliers china could also be affected.

Praseodymium (III,IV) oxide is the inorganic compound, chemical formula Pr6O11, submicron and nanopowder forms may be considered for industrial and application purpose. The appearance of Praseodymium Oxide is dark brown powder. It mainly applied in the chemical catalysis, and is often used in conjunction with a promoter such as sodium.Important discoveries have been made in the study of anticancer drugs inhibiting the growth of gastric cancer cells in my country. According to "Science and Technology Daily", a research report provided by Ai Jun and others from the Fourth Hospital of Hebei Medical University showed that seven anticancer drugs including cisplatin had obvious inhibitory effects on gastric cancer cells (BGC-823) in vitro. However, there are certain differences, and it is ideal to use a medium concentration for 48 hours.
