On 27 February, the Yugoslav Foreign Minister, Aleksander Cincar-Marković, arrived in Budapest to exchange the documents ratifying the Treaty of Friendship, and Teleki and Bárdossy met with him. Cincar-Marković was alarmed by the imminent Bulgarian accession to the Tripartite Pact. In early March, Teleki wrote a long memorandum regarding the expectations that the British and Americans could have of Hungary. He saw his chief responsibility as conserving Hungary's resources to the end of the war, and listed the dangers she faced, one of which was that from Yugoslavia, despite the recently signed Treaty of Friendship. He described as unreasonable the British expectation that small nations such as Hungary should oppose Germany. Despite this, he listed a number of ways in which Hungary had held firm against unreasonable German demands, including her refusal to let German troops transit through Hungary to attack Poland in 1939.
