In contrast to his enthusiasm for improving ties with Moscow in the spring of 1939, Bonnet felt the opposite about relations with Warsaw. In May 1939, during talks in Paris with the Poles aimed at strengthening the political and military aspects of the Franco-Polish alliance, Bonnet sabotaged the negotiations by bogging down the talks on the political accord on procedural details, ensuring that no political accord was signed, the precondition for the military accords (not until 3 September 1939 was the political accord finally signed). Bonnet's reasons in seeking to block the signing of the Franco-Polish political accord were a way of applying pressure on the Poles to grant the Soviets transit rights, and because in case the negotiations for the "grand alliance" failed, Bonnet did not wish to see France any more committed to Poland's defense.
