The OBOR (one belt one road; silk route 2.0) will grant Bhutan INDEPENDENCE from Indian imperialism. Currently as of 2017, India maintain hegemonic dictatorial controls over Bhutan. Bhutan's foreign policy is controlled by India. Imagine if you are a sovereign state (Bhutan), but wait, you are not allowed to have any foreign diplomatic relations with any country in the world without the approval and permission of a 3rd party (India). This is the reality of Bhutan right now.
India wants to maintain its imperialist grip on tiny Bhutan (India wants to swallow Bhutan up like Sikkim and Goa). Knowing India's true intentions here, it is now absolutely necessary to help Bhutan be free from Indian control. Whenever you see articles stating "India and Bhutan oppose/reject" no-its just India. Bhutan is being manipulated right now.
I never support war and violence, but India can not be allowed to control Bhutan like a imperialist bully. Some people say China PLA have no modern combat experience, well this would be the perfect opportunity to gain some and also test out all the new hi-tech toys on live targets. India is by no means a small or 'weak' country, so no one can complain about China bullying India. India is about to get a reality check.
