Yandex.Market kinda corresponds to Google Shopping. http://www.google.com/shopping Curiously enough, Google doesn't provide Shopping in Russia: there's no 'Shopping' tab when searching through google.ru, and when browsing via Russian IP, google.com does redirect through google.ru.

While we are on AdWords/Yandex.Direct, is there any alternative to Wordstat from Google? http://wordstat.yandex.com/#!/?words=iPhone

Yandex.Market has a great API that lets shops integrate with it. Some shops even manage to exist without having their own websites. They just sell through Yandex.Market. Google Shopping does not even come close.

Yandex market is awesome. It has a very detailed database of products, and lets you filter them by tons of tech specs and actually explains what they are. I use it all the time to find products in categories that I don't know much about. Amazon, Google shopping or whatever don't even come close.

You can switch by clicking a link at the bottom, "Use Google.com".

As for shopping, interestingly, it works here: "Online stores shipping to Moscow, Russia", but it's quite simplistic. Yandex.Market is more like Amazon if you look at its parametric search and filters.

I can switch, but for that I need to go explicitly to goole.com (it redirects to .ru), click "Use Google.com" and search. As opposed to searching right from the browser address bar.

Shopping works if you use google.com, but if you use google.ru - it isn't there.

Going by the description, Wordstat seems similar to Google Trends. And AdWords has several keyword research tools.
