JASB is a quarterly journal supported by Chinese As- sociation of Animal Science and Veterinary Medicine （CAAV）. The purpose of the joumal is to introduce Chinese research achievements of animal science and technology world over, and to strengthen academic communication between China and other countries. Subjects of the joumal are related widely of animal science such as： animal genetics and breeding, reproduction and physiology, biotechnology, nutrition and feed processing, environmental protection and grassland management.展开更多

Availing ourselves of this opportunity, we sincerely wish our readers a happy and prosperous New Year! China International Studies began its publication last December. Since its inception, various think-tanks and institutions of higher learning both at home and abroad as well as Chinese embassies in foreign countries and foreign embassies in Beijing have offered it great support. Many readers wrote to us giving their encouragement on this new-born publication. We are carrying some of the messages in this issue to express our deep appreciation. Articles in this issue are mainly on the Middle East situation, the Iran nuclear issue, China-EU relations, China-India relations and China’s peaceful diplomacy. We are also publishing a paper by a foreign scholar for the first time.展开更多
