Translated by Shinji Okuyama. A set of four books on geopolitics. All books are unread, so the contents are in very clean condition. They have been stored on a bookshelf, so there may be minor deterioration such as scratches on the surface. Please check the condition in the photos, and feel free to ask any questions if you have any concerns. ① The Evolving Geopolitics / Colin Gray ② The Geopolitics of the Coming Age / Colin Gray ➂ The Rise and Fall of China / Edward Luttwak ④ China 4.0 / Edward Luttwak
