He also said it was a pity that Washington chose Brunson over Turkey, its partner in North Atlantic Treaty Organisation, and in an opinion piece published in the New York Times, he warned the U.S. that Ankara had other alternatives as allies.
The ailing Turkish lira, which had already lost one third of its value this year largely over worries about Erdogan's wider control of the economy, crashed further to a fresh record low, at one point losing 18 percent, its biggest fall since 2001.
On June 21, Turkey's retaliatory tariffs went into effect on 4 to 70 percent of more than $1 billion worth of US goods. But those talks on Thursday showed no signs of breakthrough.
Turkey then retaliated by slapping import duties on $1.78 billion worth of US products, including coal, paper, nuts, whiskey, autos, machinery and petrochemicals.
Turkish President Recep Tayyip Erdogan has lashed out against a shadowy worldwide "interest rate lobby" which he suggested was "campaigning" to harm Turkey's economy, after the lira fell more than 14 percent overnight.
U.S. President Donald Trump and Turkish President Tayyip Erdogan gesture as they talk at the start of the North Atlantic Treaty Organisation summit in Brussels, Belgium July 11, 2018. Brunson was among many foreign nationals detained by Turkish President Erdogan in the wake of a failed 2016 coup attempt.

He also said increasing production, exports and employment was the best response to the country's challenges.
The lira tumbled 13% in one day, to 6.51 per United States dollar, a massive move for a currency that will make the Turkish poorer and further shake global investors' confidence in the country.
The currency has fallen 66 per cent since the start of the year, pushing up the cost of goods for Turkish people and shaking worldwide investors' confidence in the country.
Relations between the United States and Turkey have not been helped by Turkey jailing an American citizen for an alleged attempted coup in 2016.
The United States has increasingly used economic sanctions against foes such as Iran or North Korea but it is highly unusual for an administration to impose import tariffs over political or judicial issues with other countries.
The Washington Post newspaper said the USA administration was doing everything to strengthen its hand in the Brunson case, but the decision would do nothing but cause more problems for bilateral relations.
