The shortage of global leaders has become a significant constraint for many organizations in the global arena. The need of developing global leaders with adequate intercultural competencies has become obvious. Many studies provide the cross-cultural competency taxonomies, rather a theory to conceptualize intercultural competencies for developing global leaders. The problem remains unsolved and becomes more complex. In the present paper, it is proposed that social constructivism is a useful theoretical foundation to develop intercultural competencies for developing global leaders.
