Since the inception of USBLA Office at Yangli Mission Centre, the organization aims to advance its infrastructural development for the welfare of the Sangtams in general and Yangli community in particular. This has led the Development department to construct residential quarters, establish schools and colleges for educational development. This particular branch of ministry under USBLA acts as an agent to educate Sangtams in the rural and urban areas about economic sustainability and self reliance based on their natural resources available.
