The Kremlin said today that Russia is open to foreign investment following a Wall Street Journal report that US President Donald Trump, for peace in Ukraine, includes significant proposals for investment in Russian rare earths and Russian energy.

The newspaper said the plans were explained in detail in annexes to peace proposals submitted to European partners in recent weeks.

They include a plan to restore Russian energy flows to Europe and for U.S. financial firms and other businesses to use $200 billion of frozen Russian state assets for projects in Ukraine, according to the paper.

Russia, said Kremlin spokesman Dmitry Peskov, is interested in foreign investment. Asked about U.S. proposals for asset freezes mentioned in the newspaper’s report, Peskov declined to comment.
