SYKTYVKAR, April 5. /TASS/. Rusal expects that Russia will challenge new US duties on aluminum through the WTO, the company's president Vladislav Soloviev told reporters on Thursday.

"We expect that Russia, through WTO mechanisms, will file appropriate complaints against this decision. We are working on different options for protecting the interests of our American clients, but within the US, the process for protecting their interests should be initiated by the consumers that receive products form us. I am sure they will do it," he said.

The United States has introduced new duties on steel and aluminum products from March 23 - 25% for steel and 10% for aluminum. Russia said it could challenge the US decision in the WTO.

The duties apply to all countries that supply products to the US, but the countries of the European Union, as well as Australia, Argentina, Brazil, Canada, Mexico and the South Korea received a postponement until May 1.
