Studying abroad between U.S. and other countries up - going both ways

The latest data on study abroad of international students coming to the U.S.A. and U.S.A. students going abroad rose this year, with the net annual impact on the American economy at 24 Billion USD.  The summary indicates that China and Saudi Arabia are the fastest growing student populations and that U.S.A. students are primarily studying in Europe, a little in Asia (China, Japan, S. Korea), and a little less in South America.

Cross-border education continues to grow - what about its impact in positive diplomatic relations and trustful cross-cultural cooperation?
