That’s the view of a Chinese strategic expert. The funniest part is:

China can give political support to Bangladesh enabling the latter to encourage ethnic Bengalis in India to get rid of Indian control and unite with Bangladesh as one Bengali nation; if the same is not possible, creation of at least another free Bengali nation state as a friendly neighbour of Bangladesh, would be desirable, for the purpose of weakening India’s expansion and threat aimed at forming a ‘unified South Asia’.
