Speaking ahead of a cabinet meeting on Tuesday, Tusk said he was confident the agreements with Taiwan would be finalised in the autumn.
"Cars and semiconductors," he summarised.
The semiconductor factory will be built on land originally prepared for an Intel facility.
The US chipmaker pulled out of a planned USD 4.6 billion investment there in July 2025.
Tusk said talks with Foxconn on the semiconductor plant were also in their final stages.
"We have already invested money there, and we will have a semiconductor factory in Lower Silesia with the same Taiwanese partner," he said.
On the EV side, state-owned ElectroMobility Poland (EMP) is developing a factory in Jaworzno in southern Poland with Foxconn's subsidiary Foxtron.
The plant is expected to produce three mid-sized SUV models, with Poland holding exclusive sales rights across Europe.
"We will be building a great hub in Jaworzno, integrated with the entire industrial and technological ecosystem in the area," Tusk said.
The first car is due off the production line in 2029.
A joint venture agreement is expected to be signed this autumn, with construction in Jaworzno set to begin in spring 2027.
The project will be financed by PLN 4.5 billion in loans from EU recovery funds.
EMP was founded in 2016 to develop a Polish electric car brand called Izera, though earlier plans, which had involved Chinese partners, repeatedly slipped and were never realised in their original form.
Under the new arrangement, Foxtron will provide the initial vehicle platform, with Polish engineers expected to contribute 70 percent of the design work on the second-generation model.
Taiwan's electronics industry association TEEMA has identified Poland as a priority investment destination, focusing on semiconductors and the tech sector, with Wrocław, Katowice and Łódź at the centre of that push.
