  The topic of this conference is 'South-South and North-South Collaboration in
Science and Technology', which is addressed in this contribution in the context
of basic research in high energy physics (HEP). The question whether developing
countries can or should invest scarce resources in big science is not covered.
HEP may be less expensive than one might fear, but cheap it is not, so
priorities have to be set and these may indeed differ from country to country.
The scope of this article is not to argue one way or another, but rather to
give an indication and practical examples of both the requirements and the
opportunities for scientific collaboration with CERN.
