Acting US Defense Secretary Mark Esper is making it clear to Turkey that it will face economic sanctions if it goes ahead with the purchase of a Russian missile defense system.
Esper met with Turkish Defense Minister Hulusi Akar on Wednesday during a NATO meeting. Officials say there was no progress in the stand-off between the two allies.
Russia will make first delivery of the S-400 missile systems to Turkey in July, Russian news agencies cited the head of Russian state arms exporter Rosoboronexport saying on Wednesday, in accordance with the earlier-stated plans.
"We are making first delivery in July as part of out plans," Alexander Mikheev is quoted as saying by RIA news agency.
The repeated provocations by Turkish President Tayyip Erdogan especially in Cyprus' EEZ will obviously continue.
Pressured by domestic problems, not the least of which is the loss of the Istanbul mayoralty which was the first major defeat in his career, he is resorting to nationalist salvos and provocations to rally his political base.
