The economic effects of the conflict in Europe, according to British Prime Minister Boris Johnson, might put pressure on Ukraine to reach a peace agreement with Russia that is not in its best interests.

"Too many countries are saying this is a European war that is unnecessary... and so the pressure will grow to encourage - coerce, maybe - the Ukrainians to a bad peace," Johnson told news anchors in the Kigali, the capital of Rwanda, where he attended a Commonwealth summit.

Johnson said the consequences of Russian President Vladimir Putin being able to get his way in Ukraine would have "a long-term economic disaster" and will be a danger to international security.

Earlier, on the first day of a trip to Kigali, which is hosting a Commonwealth summit this week, he praised Rwandan President Paul Kagame and his tiny African country's achievements, despite widespread concerns about its human rights record.

It is worth noting that the London-Kigali scheme, which involves Britain deporting asylum seekers to Rwanda thousands of miles away, has sparked outrage.

However, Johnson told reporters, "The critics need to keep an open mind about the policy."

Furthermore, Johnson praised Rwanda's "moral stance" on the war in Ukraine, according to a statement issued by his Downing Street office following his meeting with Kagame.

The two men talked about how to deal with the fallout from the war in Ukraine most notably the sharp rise in food prices that has hit African countries hard.
