France recalls ambassadors from Aus and US over submarine deal
They also cancelled a gala to celebrate France-US relations, and is now reportedly trying to convince other EU countries to pull out of talks with Aus over a proposed free trade agreement.
The original 2016 deal for 12 French subs was to be estimated $25b, which grew incrementally, finally to $90b, and was behind schedule. $300b would have been the total cost including maintenance for subs not ready till between 2035 - 2050, and there are questions how outdated they might be then.
Something about China stepping up aggression in the oceans, and Aus looking at buying from the US/UK.
