The Indian Army has used tanks originally designed and built in many countries. Which of these countries has India never bought tanks or a license for production?

Germany. India's tank arsenal, some of it inherited from the British World War 2 stock post-Independence, has included tanks from the above countries, except Germany. While British and French tanks, such as the Centurion and AMX-13, plus a few vintage Shermans, formed the pride of Indian armour in the 50's and 60's, Soviet tanks such as the T-55, T-62, T-72 (in large numbers) and most recently the T-90, have formed the majority of India's armoured corps since the 70's.
