With a war raging and food prices soaring, Trudeau attends Commonwealth summit in Rwanda

The war in Ukraine will cast its shadow over Prime Minister Justin Trudeau and other Commonwealth national leaders as they arrive in Kigali, Rwanda on Wednesday for their first meeting since the onset of the pandemic.

Food security — particularly in Africa — is expected to be a major topic of the leaders' conference. So is the fact that multiple major countries abstained from a resolution condemning Russia's invasion of its Eastern European neighbour at the United Nations earlier this year.

In an interview with CBC Radio's The House, Trudeau said the challenge facing Ukraine's allies is to engage "in a very, very real and sustained way" with leaders who are skeptical of sanctions to make them "understand that Russia is trying to destabilize the world and set democracy and the rule of law back by decades."

"It's important for everyone, not just European countries, that we be standing up to that attempt to redraw the world order," he added.

Ten Commonwealth members — Bangladesh, India, Mozambique, Namibia, Pakistan, South Africa, Sri Lanka, Tanzania, Uganda and Zimbabwe — formally abstained from a UN vote last March which condemned the Russian invasion of Ukraine on Feb. 24.

While not legally binding, resolutions of the UN General Assembly carry political weight.

Trudeau said there's an argument to be made to convince India and South Africa — which he said " pride themselves very much on principles of democracy, principles of territorial integrity, of sovereignty, of a people being able to determine their own future" — to push back against Russia's war on Ukraine.

It remains to be seen how effective those arguments will be. India, for one, has been buying discounted Russian oil and coal at an increasing rate.

India is the world's third-largest consumer of oil and over 80 per cent of it is imported. Moscow was not a major supplier of oil to India before the invasion. In January and February of this year, India did not import any crude from Russia at all.

Today, Russia is India's second-largest source of oil.

The Commonwealth meeting, Trudeau said, will be an opportunity to remind countries that "they don't have to make nice with Russia" and to underline the fact that Moscow is the "instigator of all this instability" around the world, particularly regarding food security.

Ukraine and (to a lesser extent) Russia are among the biggest suppliers of grain to Africa, where food prices are now soaring.

Russia has tried to blame western sanctions for those price spikes. Trudeau pointed out that the sanctions on Russia do not affect shipments of food and grain.

Much of Ukraine's grain for export is still stuck in the country because its ports have been sealed off by a Russian naval blockade.
