President Recep Tayyip Erdogan yesterday said Turkey would boycott US electronic goods like the iPhone in retaliation for punitive sanctions from Washington, as the Turkish lira finally clawed back some ground after going into a tailspin over the tensions, reports AFP from Istanbul.

The dispute between the NATO allies—brought to a new intensity by Turkey’s holding of an American pastor for two years—has raised questions over the future of their partnership and fanned fears of a looming economic crisis in Turkey.

“We will boycott US electronic goods,” Erdogan said in a speech in Ankara, again showing no sign of compromise in the dispute.

“If (the United States) have the iPhone, there’s Samsung on the other side,” he said, referring to US giant Apple’s iconic phone and the top South Korean brand.

“We (also) have our Venus and Vestel,” he said about homegrown Turkish electronics brands.

Shares in Vestel zoomed up seven percent on the Istanbul stock exchange after Erdogan’s remarks.

Erdogan has been repeatedly photographed with Apple products including the iPhone and iPad.

He also made his now famous speech on the night of the July 2016 failed coup calling citizens out into the street through FaceTime, an iPhone app.

Some joked bitterly on social media that the plunge of the lira would make Apple products unaffordable for Turks in any case.

The lira’s plunge—which had been ongoing for weeks—was turned into a rout on Friday when US President Donald Trump tweeted that Washington was doubling aluminium and steel tariffs for Turkey.

Turkish Airlines also announced on Twitter that it would join a campaign circulating on social media with a hashtag #ABDyeReklamVerme (don’t give ads to America).

“We, as the Turkish Airlines, stand by our state and our people. Necessary instructions on the issue have been issued to our agencies,” Yahya Ustun, spokesman for the country’s flag-carrier, wrote on Twitter.

Erdogan said Turkey was facing an “economic attack” and a “bigger, deeper operation”.

“They don’t hesitate to use the economy as a weapon,” he said. “What do you want to do? What do you want to achieve?” he added, referring to the US.
