Again the two countries were cut off form each other and the tourism in the following one and a half decade were basically non-existent, so beside politics there weren't much contact between the two nations. But the events of 1956 showed the living sympathy and camaraderie between us. For the similar societal background both nation reacted similarly to the forced stalinization, in '56 first the Poles had an uprising in Poznan, then for the popular demand a softer government was installed in Poland by the Soviet. Our protests in October were organized as a sympathy movement toward the Poles, and these protests turned into the Revolution and then and independence war. Polish reaction followed, they also held protests in solidarity.
From the 60s our economy became more free, here people even could buy certain western goods. The whole Block everyone came here to do their shopping, among them Poles. But Poland offered a more liberal cultural and intellectual atmosphere, displays of modern art and cinematography, so people went there on holidays, Poland meant a window to the world. By the '80s the "underground" opposition also had ties, risky documents and books were published in the other country, for example documents of '56 in Poland, but documents of Katyn in Hungary.
After the regime change we remained on the same course, NATO, EU. The V3 was resurrected again, and now it's V4. Tourists come and go, and our workers do their job together in Western factories if the choose to move there. We have streets named after Polish people and places, statues and monuments in commemoration of past events. We have this Friendship Day, and some official gestures always made (e.g. Orbán when won the election, as a PM he visited officially Warsaw first).
