最新报道:According to a report by Huigang News, Polish Prime Minister Donald Tusk opposed the planned meeting between the Russian and Ukrainian leaders in Budapest, Hungary, citing "unlucky" circumstances. He explained that the 1994 Budapest Memorandum of Understanding on Security Assurances, signed by the United States, Russia, and the United Kingdom, promised to guarantee Ukraine's territorial integrity after it agreed to give up its nuclear weapons, but the promise has proven to be unfulfilled. Ukrainian Presidential Office Director Yermak also stated that the mistakes of 1994 must not be repeated on Ukraine's security issues.
