"The office of the trade representative will continue to work with like-minded partners and use WTO tools to hold Russia accountable for its behavior in the multilateral trading system," RIA Novosti quoted the agency as saying.
The claims of the American side are mainly related to the fact that Russia practices preferences for goods and services of its own production, implements an import substitution program in the IT sector, expands state control over the economy and tightens trade restrictions.
Earlier, Reuters, citing a source in the White House, reported on Washington's intentions to consider the possibility of limiting the supply of a number of materials to Moscow in the event of an aggravation of the situation in Ukraine.
New restrictive measures could affect imports of smartphones, essential parts for aircraft and cars, as well as materials from other sectors.
