"Hình thành một tổ chức"
Translation:Form an organization
Thành lập is usually translated as 'to establish'. There is a difference in that 'to form' just means 'to take shape' while 'to establish' generally means more of 'to start/set up something' that's intended to be long-lasting.
Establish an organisation would be better here but they've chosen to use to form.
