Nagao Ken said that because the cooperation between India and the United States is weaker than that of Japan, the United States, the United States and Australia, China believes that if it attacks India, the other three countries in the Quad may not come to help India. He pointed out that although China has been sending the message to India that "it is useless to support the Quad, and the United States, Japan and Australia will not assist India at critical moments", India obviously chooses to deepen security cooperation with the Quad, which will undoubtedly have a concrete impact on the Indo-Pacific strategy. Impact.
Zhang Jing, a senior researcher at Taiwan's Chinese Strategic Society, said in an interview with Voice of America that the Japanese Self-Defense Forces and the Indian military have built a considerable degree of mutual understanding and specific experience through a number of military exchanges and joint military exercises. As far as military coordinated operations are concerned, both sides will indeed get positive bonus points. However, as for the first joint exercise in Japan, it may be difficult to have any specific impact on the essence of the Indo-Pacific strategy held by both Japan and India.
According to Zhang Jing, Japan has been using the Blue Book of the Ministry of Foreign Affairs and publishing a document called 'Free and Open Indo-Pacific' multiple times. They claim that it's a Japanese foreign policy strategy, but it's not clear what exactly it entails.
Prioritize military exchanges and coordinated operations with India. The Indian government has never put forward any policy statement on the Indo-Pacific strategic concept; therefore, it is obviously difficult for the joint military exercises of the two sides to specifically affect any basic stance of the Indo-Pacific strategy.”
Zhang Jing believes that in principle, such transnational joint military exercises are important achievements in military affairs and diplomacy, and because terrorist activities are regarded as a common enemy by the international community, so Japan and India’s joint military exercises aimed at countering terrorism will have a negative impact on the international image of the two countries. Naturally, there are bonus points. As far as playing the image card to gain international reputation, it is absolutely guaranteed to make money without losing money, but it does not mean that Japan or India's current foreign policies have significantly changed.

Joint exercises may be beneficial to familiarize yourself with each other's armaments
In this joint exercise, the Japanese Ground Self-Defense Force sent the 36th General Division Company stationed in Itami, Hyogo Prefecture to participate in the training, and the Indian Army sent anti-terrorism troops to participate. The training content set the city under attack street fighting, will deploy helicopter troops and training on the disposal of explosives. During the exercise, the Indian Army will operate the Tekken anti-tank rocket launcher of the Japanese Ground Self-Defense Force, and take a Japanese unmanned reconnaissance vehicle to transport the wounded.
A month ago, Japan and India began their first joint fighter jet training at the Baili Air Force Base northeast of Tokyo on January 16. The Self-Defense Forces sent 4 F-2 and 4 F-15 multi-purpose fighters to participate, and India sent 4 Su-30MKI fighters, 2 C-17 transport aircraft, an IL-78 air tanker and about 50 personnel to participate. The Su-30MKI fighter will be equipped with the latest supersonic cruise missiles, which can reach inland China.
The Self-Defense Force statement stated that the purpose of the joint military exercise is to "strengthen defense cooperation among air forces and improve the tactical skills of the Self-Defense Forces." India said the exercise included training for air combat missions in various complex environments, and paved the way for improving the joint combat capabilities of the air forces of the two countries.
Analysts believe that the frequent and all-round joint exercises between Japan and India are conducive to mutual familiarity with Russian-made and American-made armaments.
Ken Nagao, a researcher at the Hudson Institute in Washington, said that taking the joint exercise between the Japanese Air Self-Defense Force and the Indian Air Force in January as an example, India's fighter jets, like those of China and Russia, are Su-30 MKI fighters, which can indeed make Japan Training how to deal with Chinese and Russian fighters. On the other hand, the US-made fighters used by Japan can help India understand how to deal with attacks from Pakistan.
Then India and Japan's F-2 fighters will be able to obtain The specific experience of confronting Pakistan's F-16 fighter jets. In particular, India sent anti-terrorism troops to participate in the exercise this time. Pakistan has continued to try to weaken India's national strength with frequent terrorist attacks in recent years. Joint exercises with Japan's F-12 fighter jets are important to India. Absolutely of substantial significance.”
Xie Gang, dean of the School of International Studies, Jawaharlal Nehru University, said that although Western countries have exported arms to Pakistan, and India has also imported armaments worth more than 60 billion U.S. dollars from Russia, any buyers and sellers understand that this The core technology of such systems must not be shared with others, including Japan, so the joint exercise has nothing to do with getting familiar with the important details of the two sides' armaments.
Xie Gang believes that India will not provide any information about the Su-30MKI fighter to Japan, so these joint exercises are aimed at enhancing interoperability. He pointed out that the armed forces of Japan and India are very professional, and the focus of the exercise is on planning scenarios to deal with the chaos in the region, not on armaments.
Zhang Jing, a senior researcher at Taiwan's Chinese Strategic Society, believes that although Japan and India are old partners in military exchanges, they may not be able to look forward optimistically through the recent joint exercises to improve their level and expand their space. He said: "Because the governments of Japan and India have not established an alliance combat system, nor do they have common military principles and standard operating procedures, this exercise should be able to learn from each other in low-level basic military combat skills and tactics.

But for the high-level staff plan and the strategic guidance of the military and political system, I am afraid that neither side has any specific significance." Zhang Jing said that even so, in the process of joint exercises, allowing the Indian military to get in touch with the equipment used by the Japanese Self-Defense Forces can provide limited marketing opportunities for the Japanese arms production system, and the exchange and seminars jointly held with the joint exercises can provide An opportunity for the two sides to enhance understanding, which also has indirect benefits for both Japan and India.
