Poland’s ambassador to Japan, Jadwiga Rodowicz-Czechowska, told the Polish station TVN24 that she signed the Anti-Counterfeiting Trade Agreement, or ACTA, in Tokyo on Thursday.

ACTA is a far-reaching agreement that aims to harmonize international standards on protecting the rights of those who produce music, movies, pharmaceuticals, fashion, and a range of other products that often fall victim to intellectual property theft.

Poland’s plans to sign ACTA sparked attacks on Polish government websites and street protests in several Polish cities this week.
