This collection gathers all the essays that I have presented during about 15 years in France and elsewhere, during the colloquia of the Third World Association. These essays concern the same subject treated differently according to each period. This is why I have written a collection of essays rather than a book. However, all these essays share a common goal: economic development and political stability, especially in Asia. The challenges facing the continent in achieving full economic integration are many and varied: foreign trade, development aid, foreign investment... I myself have Japanese nationality, and it would be easy to interpret that the articles are pro-Japan or pro-Asia... However, I am concerned about impartiality. Nevertheless, in my opinion, the era of Asia has arrived, and in my last conference in Grenoble in 2018, I will explain it out loud.
