They definitely set up shop in the Netherlands. I don't think they have much interest in any kind of local "control" in the Netherlands though.

Belgium seems to have a bit more noticeable Italian OC activity. I'd say Belgian Limburg is one of the most important bases abroad for the Ndrangheta. Liege and other parts of Wallonia on the other hand are more Sicilian. They're all over though; a few years ago a Camorra member was arrested in Antwerp for raids on a few jewel shops throughout Belgium.

In 2011 Belgian intel still named Italian OC the most prevalent kind of "foreign" OC with at least 24 active criminal networks connected to the Cosa Nostra, Ndrangheta and Camorra. Italian OC was followed by Dutch, Albanian, Moroccan, Turkish (including Turkish-Assyrian and Turkish-Kurdish) and to a lesser extent "Russian" (including Russian and Georgian Jewish, Chechen, Georgian, Armenian, Azeri, Georgian Kurdish), Israeli, Chinese, Greek and Lebanese networks.
