Earlier Carney rejected the "referendum" in the Crimean region of Ukraine.
"No decisions should be made about the future of Ukraine without the Ukrainian government. Moreover, this vote was not necessary.
"The Ukrainian government has made clear its willingness to discuss increased autonomy for Crimea, and the presidential elections planned for May 25 provide a legitimate opportunity for all Ukrainians to make their voices heard on the future of their country," Carney said.
In addition, Ukraine, the United States, the EU, the OSCE, the UN, and others have called for Russia to allow international monitors into the Crimean peninsula to ensure that the rights of ethnic Russians in Ukraine are being upheld, he said.
"Russia has spurned those calls as well as outreach from the Ukrainian government and instead has escalated its military intervention into Crimea and initiated threatening military exercises on Ukraine's eastern border," he added.
Describing the Russian actions as dangerous and destabilising, Carney said the UN Security Council recognised this in a vote yesterday that only Russia opposed.
"As the United States and our allies have made clear, military intervention and violation of international law will bring increasing costs for Russia - not only due to measures imposed by the United States and our allies but also as a direct result of Russia's own destabilising actions," he said.
