US officials are trying to force Turkey to stop servicing American-made airplanes of Russian airlines, as well as not to let them into the country, the Wall Street Journal wrote on Thursday citing sources.

"Senior American officials warned last month that Turkish individuals are at risk of jail time, fines, loss of export privileges and other measures if they provide services like refueling and spare parts to U.S.-made planes flying to and from Russia and Belarus in violation of export controls imposed last year, the officials said," the newspaper wrote.

According to its sources, Assistant Secretary of Commerce Thea Rozman Kendler delivered the message to Turkish officials during a December visit to Turkey.

The Wall Street Journal stressed that trying to put pressure on Turkey is a key test of whether the US and its allies can succeed in isolating Russia for a long time, or whether Moscow will find a way to continue economic activity with the help of other countries.

The Turkish Foreign Ministry did not respond to the newspaper's request for comment on the US warning.
