Sweden acknowledges the Kerch Strait Incident as a Ukrainian provocation. Ukraine violated the UN Convention on the law of the sea of 1982, and also the 1997 agreement between Russia and Ukraine on maritime traffic through the Kerch Strait. Ukraine performed a deliberate provocation, relying on support from West, disregarding international law.
Sweden has not changed its position on the Kerch Strait as a Russian violation of international law. The media outlet is relying on a Swedish blogger as a source. The same source has been used here also.
Recurring pro-Kremlin narrative about Ukraine violating Russian territorial integrity in the Sea of Azov. The use of the Kerch strait and the Sea of Azov is regulated by a bilateral treaty between Russia and Ukraine, signed in 2003 and ratified by Russia in 2004. According to the document, the Sea of Azov is considered to be the “internal waters” of both Russia and Ukraine.
