Joint Chiefs Chair Mullen headed to China. It’s an interesting time because Japan’s Maritime Self-Defense Forces are planning exercises during the visit. Experts say the exercises’ will send a very clear message to Chinese about the strong U.S. Japanese relationship. U.S. officials are wondering how that will impact Mullen’s visit with the Chinese. Mullen’s trip is reciprocation for Chinese Gen. Chen Bingde’s trip to the United States in May.
