Malta is part of the EU, so if Zonda are importing to Malta then they presumably have met the European standard, which must be pretty formidable on a PSV - and as has been said, if they can meet that standard they can probably meet any standard if they want to. That's assuming they are actually being used on the road in Malta rather than just sitting in a compound somewhere waiting to be shipped somewhere else.
I am as wary as anyone buying Chinese-made stuff, but I think it's dangerous just to write-off any product just because it has a Chinese label on it - the truth is that there is some extremely advanced stuff made in China now, and the standard of even the mass market stuff is improving all the time. 40 years ago people were very dismissive of stuff made in Japan. 20 years ago it was Taiwan. 10 years ago it was Korea. Etc.
As some of you may know, Rover and MG were bought by the Chinese last year, and have been added to what is apparenty a very large and active car manufacturing industry in China - but so far almost all the output goes to the (vast) home market. I cannot think of any Chinese-built cars I have seen on the roads here, but I know there are some very cheap Chinese motorbikes out there.
Finally, this website has various pictures of Chinese copies of other manufacturer's vehicles. The Rolls Royce Phantom 'copy' is especially nice!http://gemssty.com/2006/10/29/top-10-copycat-cars/
