In France too. In fact I notice I know many Vietnamese descendents, but I didn't realize it until I counted. They're Frence-rooted to me. Successful integration.
I spent some months in Australia and got a completely different idea: multiculturalism is completely an illusion. It's a "timebomb" slowed down by abundance of resources: while everybody is getting more then they need, everything is ok.
Edit: For half a decade I was an expat in a monocultural country. Being open-minded (giving in more often than demanding) and member of a too small community to be considered a threat I could enjoy peace to a greater extent than everywhere else before - even as a member of the majority group in my own country. Probably that's why I'm very bearish regarding multiculturalism.
Step 2 in Australia now is mandatory detention, and step 3 happens some undetermined time later (if ever). Interesting to see how we've gone backwards.
Well, asylum-seekers are a massive political football at the moment, but they're a drop in the bucket compared to other migration - Australia has 500k in and 300k out for an annual net migration of 200k in. Excluding kiwis, permanent migrants in are about 86k. Asylum-seekers are very much in the media, but they are also very not typical of the usual migrant situation here.
With 28% of our population being born overseas, we're doing integration okay (21% if you discount UK and kiwiland - and our #1 country of import in recent years is China). For comparison, the UK is 12% and the US is 14%. If you look at the current migrant rate (migrants/1000 pop/year), there are only two sizeable western countries higher than Australia, being Norway and Spain. If you exclude conflict areas, there are no other large countries higher than Australia[1].
Basically, the WAP is dead as a dodo as of 40 years ago. The idea that Australia is an insular country afraid of immigration is clearly a myth once you look at the stats. Of course, that doesn't sell newspapers.
In short, no, we haven't gone backwards. We're actually a success story, it's just that we have a very visible wart on our nose at the moment (thank you, politics).

It worked well enough for the influx of Vietnamese refugees too.
