"We've clearly warned Turkey that its potential acquisition of the S-400 will result in a reassessment of Turkey's participation in the F-35 program and risk other potential future arms transfers to Turkey, as well as lead to potential sanctions under the Countering America's Adversaries Through Sanctions Act," Palladino said on Tuesday.
Palladino noted that the US position regarding Turkey potentially obtaining S-400 systems has not changed and Washington would like to work collaboratively on the issue of air defence systems with Turkey.
