The leaders of the G-7 countries — Canada, France, Germany, Italy, Japan, the United Kingdom, and the United States — released a scathing statement Sunday night condemning Russia's "clear violation of the sovereignty of Ukraine."

The joint statement also said that the leaders have agreed to suspend participation in the G-8 summit scheduled in June in Sochi, Russia.

Here's the full statement:

We, the leaders of Canada, France, Germany, Italy, Japan, the United Kingdom and the United States and the President of the European Council and President of the European Commission, join together today to condemn the Russian Federation’s clear violation of the sovereignty and territorial integrity of Ukraine, in contravention of Russia’s obligations under the UN Charter and its 1997 basing agreement with Ukraine. We call on Russia to address any ongoing security or human rights concerns that it has with Ukraine through direct negotiations, and/or via international observation or mediation under the auspices of the UN or the Organization for Security and Cooperation in Europe. We stand ready to assist with these efforts.

We also call on all parties concerned to behave with the greatest extent of self-restraint and responsibility, and to decrease the tensions.

We note that Russia’s actions in Ukraine also contravene the principles and values on which the G-7 and the G-8 operate. As such, we have decided for the time being to suspend our participation in activities associated with the preparation of the scheduled G-8 Summit in Sochi in June, until the environment comes back where the G-8 is able to have meaningful discussion.

We are united in supporting Ukraine’s sovereignty and territorial integrity, and its right to choose its own future. We commit ourselves to support Ukraine in its efforts to restore unity, stability, and political and economic health to the country. To that end, we will support Ukraine’s work with the International Monetary Fund to negotiate a new program and to implement needed reforms. IMF support will be critical in unlocking additional assistance from the World Bank, other international financial institutions, the EU, and bilateral sources.

The statement comes a day after Russia's parliament approved the use of military force in Ukraine, a move the West has said is a violation of sovereignty and a breach of international law.

U.S. Secretary of State John Kerry accused Russian President Vladimir Putin on Sunday of a "stunning, willful choice" to invade another country. Kerry is traveling to Kiev on Tuesday, where he will meet with the leaders of Ukraine's new government.
