Why India did not allow Bangladesh to place Bangabandhu-1 satellite in South Asian orbit?

There is no official information or statement available to suggest that India did not allow Bangladesh to place the Bangabandhu-1 satellite in the South Asian orbit. In fact, India has been supportive of Bangladesh's space endeavors and has collaborated with them in various space-related projects.

Bangladesh's first-ever satellite, Bangabandhu-1, was launched on May 11, 2018, from the Kennedy Space Center in Florida, USA, using a SpaceX Falcon 9 rocket. The satellite was placed in the geostationary orbit at 119.1° East longitude, which is outside the South Asian orbit.

It is important to note that the South Asian satellite initiative, known as the South Asia Satellite or GSAT-9, was launched by the Indian Space Research Organisation (ISRO) on May 5, 2017. This satellite was primarily intended to provide communication and disaster support services to the South Asian Association for Regional Cooperation (SAARC) member countries, including Bangladesh.

While Bangladesh did not participate in the South Asia Satellite initiative, it does not imply that India did not allow them to place their satellite in the South Asian orbit. The decision to launch and place satellites in specific orbits depends on various factors, including technical requirements, international agreements, and the capabilities of the launching country.
