US President Donald Trump said, on 10 August, that he had doubled steel and aluminum tariffs on Turkey, adding to pressure on Turkey's troubled economy amid a diplomatic row with Washington."I have just authorised a doubling of Tariffs on Steel and Aluminum with respect to Turkey as their currency, the Turkish Lira, slides rapidly downward against our very strong Dollar!" Trump said on Twitter."Our relations with Turkey are not good at this time!" Trump's announcement came as Turkey's embattled lira hit new record lows against the US dollar and euro, losing nearly nine percent in value as strains with the United States showed no sign of abating and fears grew over the exposure of European banks.However, the White House later clarified that Trump's announcement "authorised the preparation of documents" to raise the tariffs.

Harsher US tariffs were likely to punish Turkey's already faltering steel exports to the United States.In the first three months of 2018, Turkish steel exports to the United States fell nearly 50 percent over the same period in 2017, making it the only top-10 source of US steel imports to see a decrease, according to the US Commerce Department.Trump Urges End to Russia Probe as Manafort Trial Enters Day Two We'll get through this!
