A Hint...

 ... which is not really a hint but an order))

Russia could place restrictions on the supply of certain strategically important raw materials to the global market, President Vladimir Putin stated on Wednesday. He said exports of nuclear fuel, metals, and minerals could all be affected. The move would be a response to Western attempts to block Russia’s access to certain foreign-made goods, Putin said. ... At a government meeting on Wednesday, Putin said that despite Western restrictions, Russia continues to supply some types of goods to the world market “in large quantities” and in some cases buyers are happily stockpiling Russian products. At a government meeting on Wednesday, Putin said that despite Western restrictions, Russia continues to supply some types of goods to the world market “in large quantities” and in some cases buyers are happily stockpiling Russian products. “Russia is a leader in terms of reserves of a number of strategic types of raw materials... Yet we are limited in the supply of a number of goods – maybe we should also think about certain restrictions,” the president said. He suggested that the proposed restrictions could include the country’s exports of uranium, titanium, and nickel, as well as “certain other goods.”“There is no need to do anything to harm ourselves… I am not saying that we need to do this tomorrow. But, in general, if this will not harm us, we could think about certain restrictions on supplies to foreign markets,” Putin suggested, noting that the significance of the potential move would be difficult to underestimate given the “importance of Russian raw materials.”

Obviously, two can play the game. And once these two words--titanium and nickel--have been uttered, some people at Boeing and Airbus had a bit of an anxiety attack. As per uranium--oh boy, some interesting dynamics may develop on this market, if you know I mean. So, it looks like Russia decided to shake "foundation" of the West some more.
