Macron on Monday visited the Baltic port city of Gdańsk for a Polish-French intergovernmental summit, held alongside the first observance of Polish-French Friendship Day.
Speaking at a news conference, Macron said that "among the things we will consider will be exchanges of information, joint exercises," when asked about cooperation with Poland on nuclear issues, Politico reported.
France is the European Union’s only nuclear-armed state.
Earlier this year, Macron announced what he described as "a new phase in French deterrence," signalling a shift toward greater involvement of European allies, including participation in nuclear drills.
According to Politico, the initiative could include countries such as Poland, Germany, Greece, the Netherlands, Belgium, Denmark and Sweden.
Poland, which does not participate in the US nuclear-sharing programme, has expressed interest in strengthening European deterrence against Russia.
"We’ve decided to join a group of countries invited by France to cooperate, an exclusive group made up of countries that understand the need for European sovereignty," Tusk told reporters.
"We live in a world in which we need nuclear dissuasion capabilities," he added.
Tusk said last month that Poland was in talks with France and a group of European allies on an advanced nuclear deterrence programme.
France has emphasised that control over its nuclear arsenal would remain solely with Paris, though discussions have included the possibility of deploying French nuclear-capable aircraft in allied countries, according to the Politico report.
"In all frankness, having Rafale jets with nuclear weapons over Poland is not my dream, but I hope you do not have such plans," Tusk told Macron, Politico reported.
Macron said his team would discuss options with Polish counterparts in the coming months.
Tusk also praised France’s commitment to helping protect Poland's borders with Belarus and Russia's Kaliningrad region.
He said the two sides discussed the possibility of French involvement in securing the Rzeszów-Jasionka Airport, a key hub for military and humanitarian aid deliveries to Ukraine.
France and Poland also agreed to deepen defence cooperation in areas including space and military planning, with Warsaw planning to purchase a French military telecommunications satellite by the end of the year, Politico reported.
The Polish and French defence ministers are expected to outline a bilateral cooperation plan for 2026-2028 aimed at expanding joint military activities and coordination, according to Macron's office.
