on Nathu La, which was scheduled to reopen. The informal group, consisting of civil servants and trade experts, was headed by Mahendra P. Lama and submitted its report in 2005. The report laid down two projections, a "higher projection", and a "lower projection". The lower projection estimated border trade through Nathu La at by 2010, by 2015 and by 2020. The higher projection estimated border trade through Nathu La by 2015. India's Confederation of Indian Industry (CII) gave an even higher estimation that trade could cross USD 10 billion in a decade. These figures were also based upon policy recommendations in the paper. While the trade may not have met the study group's estimate, which 15 years later seem "over ambitious", it has benefitted the impacted areas positively. Ancillary benefits were also highlighted by the report such as revenue for truckers even with low volumes of vehicle movement. Since July 2006, trading is open Mondays through Thursdays. In 2006 India exempted 29 items for export and 15 items for import from duty. In 2012, 12 more items were added to the list. Apart from illegal items, China did not put any restrictions on the border trade in 2006. The reopening of the pass was expected to stimulate the economy of the region and bolster Indo-Chinese trade, however the result has been underwhelming. In 2008, Mahendra P. Lama commented upon the mismatch in projections and actual trade during the first two years, "this is mostly attributed to poor road conditions, nascent infrastructural facilities, limited tradable items and lukewarm attitude of the policy-makers." Road limitations also constricted the size and number of trucks that can use the route. Further, there is a large mismatch between Indian and Chinese thinking with regard to trade through Sikkim, and a large mismatch with regard to on-the-ground infrastructure development with regard to supporting trade through Nathu La. In 2010 and 2011 there were no imports from China via the pass according to Government of Sikkim data. Weather also restricts trade to about 7 to 8 months and roughly between May and November. There were concerns among some traders in India that Indian goods would find a limited outlet in Tibet, while China would have access to a ready market in Sikkim and West Bengal. A concern of the Indian government is also the trafficking of wildlife products such as tiger and leopard skins and bones, bear
