Leaders of the G-8 met at the Dutch prime minister’s residence Monday night and decided to reduce the size of their fraternity to seven.

The White House was quick to paint the meeting and its outcome as the president’s idea.

Russia was expelled from the Group of Eight leading industrialized countries before President Vladimir Putin was scheduled to host the G-8 summit in Sochi at the beginning of June — technically, Russia became its own Group of One as the others pulled out to form their own G-7. Russia assumed the presidency of the group at the beginning of the year, and soon after invaded Ukraine and annexed Crimea.

In what is called The Hague Declaration, leaders of Canada, France, Germany, Italy, Japan, the United Kingdom, and the United States, along with the president of the European Council and the president of the European Commission, affirmed support for Ukraine’s “sovereignty, territorial integrity and independence.”

“International law prohibits the acquisition of part or all of another state’s territory through coercion or force. To do so violates the principles upon which the international system is built. We condemn the illegal referendum held in Crimea in violation of Ukraine’s constitution. We also strongly condemn Russia’s illegal attempt to annex Crimea in contravention of international law and specific international obligations. We do not recognize either,” states the declaration.

The leaders said they “remain ready to intensify actions including coordinated sectoral sanctions that will have an increasingly significant impact on the Russian economy, if Russia continues to escalate this situation.”

“This Group came together because of shared beliefs and shared responsibilities. Russia’s actions in recent weeks are not consistent with them. Under these circumstances, we will not participate in the planned Sochi Summit. We will suspend our participation in the G-8 until Russia changes course and the environment comes back to where the G-8 is able to have a meaningful discussion and will meet again in G-7 format at the same time as planned, in June 2014, in Brussels, to discuss the broad agenda we have together. We have also advised our Foreign Ministers not to attend the April meeting in Moscow. In addition, we have decided that G-7 Energy Ministers will meet to discuss ways to strengthen our collective energy security.”

The declaration also hails the International Monetary Fund for its “central role leading the international effort to support Ukrainian reform, lessening Ukraine’s economic vulnerabilities, and better integrating the country as a market economy in the multilateral system.”

A senior administration official told reporters that President Obama “hosted the meeting and led the discussion.”

“All of the leaders spoke during the course of the meeting and then the president summarized the way forward at the conclusion of the meeting. And there was agreement on The Hague Declaration, which is a very strong joint statement that hits all of the key elements that we were seeking to get out of this G-7 meeting,” the official said.

“…In short, Russia is suspended from the G8 pending its current activities in Ukraine, and the necessity is now on Russia to deescalate to avoid this continued isolation from the international community.”

The official stressed that “Eastern and Southern Ukraine is the clearest trigger for these sectoral sanctions” — so, more invasion by Putin.

But “status quo” — keeping Crimea — “could mean more sanctions. Well, it depends on how that status quo evolves, to be completely candid with you.”

“…So we believe we’ve imposed a cost and we’re going to continue to impose a cost for what they’ve done in Crimea. They’ve been suspended from the G8. They’ve been isolated politically as well as economically.”
