This article reviews some of the ethical aspects of collaborative research. Scientific collaboration has known potential benefits but it’s a challenging task to successfully accomplish a collaborative venture on ethically sound grounds. Current trends in international healthcare research collaboration reflect limited benefits for the majority of world population.

Successful cross-cultural and international collaborations have to overcome many regional and global barriers. Despite these difficulties, many scientific collaborations usually begin (...) with an informal meeting or contact.

Finally I conclude that scientists in healthcare research can play important roles beyond collaborations and contribute to bringing harmony, resolving differences across the nations and countries in today’s troubled world.
