India-Nepal in Assymetrical Relationship

From distant past to current unfolding of political drama, issue of nationalism has always become easy and handy tool for Nepalese political parties. It is not surprising that Baidhya-led Maoists want ban on Indian vehicles and 'obscene' movies. Nevertheless, the hardliners are partly right in that they seem not to acquiesce to unequal relationship imposed by the Indian government to the date. How come the Indian vehicles have frivolous access to Nepalese transport business and Nepalese ambulance (let alone private ones) can not enter into Indian territories!! Does not it sound little unjust? My concern is: the two nations should revise existing treaties based on equality. On doing so, initiation should be taken from both sides in diplomatic levels. Hopefully, CPN-Maoist's move would prove to be helpful rather than detrimental in taking this first step.
