ANKARA, June 29 (Reuters) - U.S. President Donald Trump told his Turkish counterpart Tayyip Erdogan that he wanted the issue over Ankara's procurement of air defence systems to be resolved without damaging bilateral ties, the Turkish presidency said.

Turkey and the United States have been at odds over Ankara's purchase of Russian S-400 defence systems, a move Washington has warned would trigger U.S. sanctions. Turkey has so far dismissed the warnings and said it would not turn back from the deal.

In a statement following talks between Erdogan and Trump on the sidelines of the G20 summit in Japan, the Turkish presidency said Erdogan had voiced concerns about U.S. actions that may harm the strategic partnership between the two NATO allies.

Turkish Daily Sabah reports:

U.S. President Donald Trump said Saturday that Turkey "was not allowed to buy Patriot missiles by the Obama administration" and his administration is looking at different solutions regarding its purchase of Russia's S-400 missiles.

"Turkey is a NATO member and was not treated fairly," Trump said in a joint presser with President Recep Tayyip Erdoğan, referring to the Obama administration's reluctance to sell Patriots to Turkey in 2013.

Asked about possible sanctions against Turkey, Trump said "we are looking at it, but it's a two-way street".
