Ukraine’s leader was denied a meeting with his most powerful ally, after Donald Trump left the summit a day early.

The Group of Seven summit in Canada has ended without leaders issuing a joint statement in support of Ukraine, as Ukrainian leader Volodymyr Zelenskyy warned that “diplomacy is now in a state of crisis”.

The summit of major industrial democracies, which wrapped up in the Canadian Rocky Mountain resort of Kananaskis late on Tuesday, had been intended to showcase unity on major global issues.

But unlike in previous years, when the group had jointly denounced Russian “aggression” against Ukraine, this time it was unable to issue a statement in support of the embattled Western ally, in a sign of growing differences within the group amid escalating global crises.

Zelenskyy met the leaders of Canada, the United Kingdom, France, Germany, Italy and Japan, along with NATO chief Mark Rutte, on the final day of the conference. However, a meeting with the leader of the group’s most powerful member, the United States – President Donald Trump – did not take place after he left the summit a day early to address the escalating hostilities between Israel and Iran from Washington.
