In 1989, Polish President Lech Wałęsa joined Cox in a Washington, DC ceremony marking the enactment of Cox's legislation establishing the Polish-American Enterprise Fund. Together with the Baltic-American Enterprise Fund, the Hungarian-American Enterprise Fund, and seven other enterprise funds in Central and Eastern Europe and the former Soviet Union, the Cox legislation, incorporated in the Support Eastern European Democracy (SEED) Act, matched U.S. foreign aid with venture capital in the newly free countries of the former Warsaw Pact. Cox has some fluency in the Russian language.
