There is nothing uplifting about it.
This is just a delaying technique to avoid sanctioning Israel due to public pressure, meant to let Israel finish executing their "Final Solution for Gaza", by which point they will pivot to saying "it's too late now".
If you read the article you'll see this "initiative" was launched by the UK PM, the very guy who has been getting people arrested for planning to demonstrated against the Genocide, so one should be incredibly suspicious (and, being familiar with British politics, the whole thing reeks of their usual "delay meaningful action by offering vague promises of future meaningless action").
Also all 3 countries still send weapons to Israel, Canada doing in the most hypocritical of ways by having a weapons export regime that says "no" riddled with backdoors so it ends up as "yes" - yet another very common tactic in British politics which one could describe as "the contents is not what it says on the box".
This way of delaying the meaningful action being pushed by public opinion is a very common technique in British politics, and during his years there heading the Bank Of England (a very political position) Mr. Carney is sure to have learned it.
Uplifting news will when there are actual sanctions against Israel in place.
