French president François Hollande has postponed a visit to Poland, after Warsaw dropped a major defence deal, reports the BBC.
Poland halted talks with French company Airbus to buy 50 of its Caracal helicopters for around 3.14bn euros (£2.8bn / $3.51bn) on Tuesday.
Warsaw said the contract was not in the country's economic and security interests.
Mr Hollande's office said foreign minister Jean-Marc Ayrault would travel to Poland instead.
The switch over the meeting scheduled for next Thursday is being seen as a display of French anger.
A visit by the French defence minister Jean-Yves Le Drian scheduled for next Monday has also been cancelled, AFP reported.
Poland's development ministry announced that differences between the two sides had sunk the talks over the defence deal.
"Poland considers the talks for a deal to be over," it added. The proposed package included an agreement that France would invest in Poland to offset the cost of the helicopters.
