In March 1940, he attended an Indian National Congress Assembly in Ramgarh, India, along with other "Thakins", including Than Tun and Ba Hein. While there, Aung San met many leaders of the Indian independence movement, including Jawaharlal Nehru, Mahatma Gandhi, and Chandra Bose, as well as the leaders of the Indian Communist Party. Aung San returned to Burma and began touring the country in June 1940 in order to promote the idea that, if Burma was invaded, the Burmese people should not support the British government. That month, while giving a speech at a village named Daung Gyi, he was warned by local policemen not to mention political events which had happened recently in the Chin Hills (which had been administered separately from Burma since 1924), which made him go out of his way to do so. On 29 June 1940, immediately after this speech, the district superintendent of police at Henzada, a man named "Xavier", issued a reward of 500 rupees issued a warrant for his arrest under the charge of sedition. By mid-1940 the Burmese government had also issued warrants for many other leaders of the "Thakins" and the Freedom Bloc, due to those organizations' efforts to organize a revolution against the British, at least partially with Japanese support.
