Ancestral relatedness and visits between national leaders: Evidence from China†

This study explores the factors that affect visits between national leaders in the world, shedding light on their ancestral origins. We combine data on visits involving Chinese leaders from 1993 to 2013 with genetic distance that captures ethnic differences transmitted intergenerationally. Empirical analysis shows that there are more visits between Chinese leaders and leaders of countries that have smaller genetic distance to China. Furthermore, the impact of genetic distance is achieved primarily through trade and positioning of political relationships, which are proxies for economic and political exchanges, respectively. Our findings show that ancestral relatedness plays an important part in modern diplomatic activities.
