>> Nepal had passed its new constitution, which favored closer ties with China over India
Nepal passed the constitution barring a large section of its own population (Madehsis et al) from participation in the government function.
This has been the bone of contention. The barred ones are culturally tied to Indian state of Bihar, almost to the extent of having common identities.
There were violent protests in southern Nepal, and slowly the situation got out of control for Nepal government to handle. The same protesters were blocking the major connecting roads from the Nepalese side of border.
While on the Indian side there were long queues of trucks lined up.
It is rumored that Indian government helped orchestrating these protests, just as much as it is rumored that Chinese government influenced to keep the Madhesis out.
But at the end of day a that constitution is certainly failing in many aspects.
I had to preempt the word and then either imagine a synonym or add a long vowel as a launching pad ...."Oh! Blackboard"
