This is not true at all, India have not put up any trade barriers. As for trucks pakistan can handle more trucks as we don't smuggle anything to pakistan but we have to thoroughly search and check trucks from pakistan for security reasons and to stop fake currency smuggling.
The proof that India don't have any barriers is the following news that India imports 7,22,967 Metric ton of cement from pakistan.
"According to All-Pakistan Cement Manufacturers Association figures, while cement import stood at 11,316 MT in September 2007, when it first began, it shot up to 89,432 MT in May 2010. From July 2008 to June 2009, cement export to India was 6,34,456 MT while in the corresponding period in 2009-10 it rose to 7,22,967 MT."
India, Pakistan 'cement' ties - India - The Times of India
If there are barriers how pakistan is exporting its cement to India?????????
And mind it that our own cement industry is facing loss as we are importing Pakistani cement because its cheaper.
