Top adviser to Turkey’s President Recep Tayyip Erdogan Ibrahim Kalin spoke with US President Joe Biden’s national security adviser Jake Sullivan for nearly an hour on Tuesday in the first official communication between the NATO allies since former President Donald Trump left office.
Sullivan and Kalin discussed building US-Turkey ties and “managing disagreements effectively,” according to a White House press release. Relations between the two allies have been remained thorny since Turkey’s purchase of Russia’s S-400 air defense system in 2017, a matter Sullivan discussed with his counterpart on Tuesday.
