According to the corresponding decree signed by Ukrainian president on Sept. 17, it comes into force from the day of its publication.
Aug. 28, Poroshenko said he expected the Foreign Ministry to submit a package of documents to start the procedure for terminating this Treaty. On Sept. 3, he said he intended to send Russia relevant notification on the termination of the treaty by Sept. 30.
The Treaty on Friendship, Cooperation and Partnership between Ukraine and Russia was signed on May 31, 1997 for a period of ten years (with subsequent automatic prolongation of the document, if the parties do not speak against it). The Verkhovna Rada ratified the document on Jan. 14, 1998 and the State Duma ratified it on Dec. 25, 1998. The treaty took effect on April 1, 1999.
Under Article 40 of the treaty, it is signed for ten years. The treaty is automatically prolonged for the next ten-year periods if none of the parties announced its wish to terminate it at least six months prior to the end of the next ten-year period. The first ten-year period began on the date the treaty took effect (on April 1, 1999) and it expired on April 1, 2009. None of the parties announced a wish to terminate the treaty before October 2008 then and therefore it was automatically prolonged for the next ten-year period.
The Treaty on Friendship, Cooperation and Partnership between Ukraine and Russia outlines the principle of strategic partnership, recognition of inviolability of the existing borders, respect for territorial integrity and mutual obligation not to use the countries' territory to hurt each other's security.
