In early March, Deputy Secretary of State Wendy Sherman arrived in Turkey for talks. In an interview with Habertürk, she called the S-400 situation a "long-term problem". “Maybe it's time to solve this problem, look for another way. At this point, we'll see what can be done. It all depends on the circumstances,” the diplomat said.

Interlocutors told Reuters on March 20 that Washington raised the possibility of sending S-400s to Ukraine in February. Experts interviewed by the agency felt that Turkey is more likely to reject such terms of the deal. Sources in Turkey told Reuters that Ankara considers them inappropriate because of the unwillingness to spoil relations with Moscow and likely technical difficulties.
