I am not sure there is one single, global answer on this. As a European, we usually use various, country level providers. A few vendors such as Harte Hanks might be able to provide global answers, but it really depends on the depth of infirmation you are looking into.
D&B/Hoover's does well with company data globally.
For contact level, you will have to go with local country vendors. If you have partners or distributors in the various regions, I would lean on them to identify those vendors.
The other way to go is to purchase lists from tradeshow and conferences that are more regional to those countries.
