Secretary of State in the Polish President's Office Krzysztof Szczerski said this after talks between Polish President Andrzej Duda and German Chancellor Angela Merkel in Warsaw on Tuesday, PAP reports. "Both the President and the Chancellor have noted that it is impossible to agree on a long-term occupation of a sovereign state. It is impossible to agree on a transition to normal contacts "business as usual" [with Russia] after the situation that happened in Ukraine until the conflict is resolved and the international order in Ukraine is restored, which is based on the international law," he said. According to Szczerski, Duda and Merkel have expressed concern about recent developments in Ukraine and that the situation is getting worse.
