Ford added in its statement that it's committed to "growing its USA vehicle lineup - including introducing all-new trucks, utilities, hybrids and fully electric vehicles".
Trump declared victory on Sunday, writing: "This is just the beginning".
"[Ford can make Focuses] in many other plants around the world, so if they made a decision to continue to sell a Focus variant in the U.S. market, there are several options other than building it in the United States".
For President Trump, this is the second tweet aimed at American companies in two days.
The company said about 80% of the vehicles Ford sells in the United States are built domestically.
In April, Ford announced plans to stop making cars in the United States - except for the Mustang - and to focus on more profitable SUVs.
Ford has traditionally produced a range of sedans, including the Focus, Taurus and Fiesta.
Syria threatened with 'stronger response' if it uses chemical weapons in Idlib
President Trump has threatened to launch a massive attack against Assad if he carries out a massacre in Idlib, the WSJ reports. Many of Idlib's residents have already fled fighting in other areas of the country during Syria's seven-year civil war.
Auto industry analyst Ed Kim told the Guardian that Trump's tariffs have, effectively, ruined Ford's plan for the Focus.
"Without the tariffs, the business case was pretty solid for that model in the United States market", Kim said.
Mohan also predicted that Apple would need to raise prices by 8 percent if it shifted 10 percent of its manufacturing to the USA - which he called the "most likely" scenario.
"This forces Ford to forfeit the sales they would have had if they could continue to import that low-volume niche vehicle", Gabrielsen said. While it is debatable whether or not Trump's trade war has helped the U.S.in any way so far, most economists believe that the idea to start this economic war is a bad one.
Some background: The first tariffs on $34 billion worth of Chinese goods went into effect back in July.
On Friday, Trump said he was ready to levy additional taxes on practically all Chinese imports, threatening duties on $267 billion of goods over and above planned tariffs on $200 billion of Chinese products.
China has threatened retaliation, which could include action against U.S. companies operating there.
