REUTERS/Viacheslav Ratynskyi/File Photo Acquire Licensing RightsWARSAW, Sept 20 (Reuters) - Poland summoned Kyiv's envoy to the foreign ministry on Wednesday, after comments by Ukraine's president on a ban on grain imports angered the government in Warsaw, which is toughening its stance ahead of October elections. It said Jablonski also told Ambassador Vasyl Zvarych that "putting pressure on Poland in multilateral forums or sending complaints to international tribunals are not appropriate methods of resolving disputes between our countries". He did not name the countries although Kyiv has previously said the complaint targeted Poland, Slovakia and Hungary. Polish Agriculture Minister Robert Telus told state-run news agency PAP that he took Kachka's comments as a way of "calming down a certain atmosphere that had been building for two or three days".
