The dispute started in 1964 when, for the first time, the then Czechoslovakia exported its excessive production of Tokaj wine to Austria, the market that used to be solely supplied with this commodity by Hungary. The conflict of interests was settled in a bilateral agreement according to which Slovakia - at the expense of the Czech beer-related concession on Hungarian part - was only allowed to export its overproduction of Tokaj wine to Hungary (which consequently re-labeled and re-exported it). This agreement expired in 1990 after which date the dispute arose again.
