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.

Tottenham Hotspur and England hitman Harry Kane has reacted on Twitter after Saturday night's 2-1 defeat by Spain in Wembley . But we want to stick to the plan and get better at it.

"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.
