"Government has achieved exactly the opposite of what it set to achieve," party spokesman Abhishek Singhvi told reporters here.
Singhvi said that it was unfortunate that the government has been making a "laughing spectacle of itself on the management of talks even before talks started" with an "imploding and ostracised" Pakistan.
Accusing the government of failing to do groundwork before the talks, he lamented that "the left hand does not know what the right is doing and head does not know what feet are doing".
Claiming that the three 'C's --Consistency, Coherence and Continuity -- are missing in Indian foreign policy under the Modi government, he asked, "Who is making India's foreign policy? Is it the PM alone? Or PM & PMO? Or IB? or NSA? Or subcommittee of four?".

Besides, he asked as to where is the Foreign Minister and the External Affairs Ministry in the making of Foreign Policy.
"Is Nagpur the remote control making India's Foreign Policy", he said in a veiled reference to RSS.
"Was it just a photo-op? What was the ground work before Ufa?", he said expressing concern that there have been "thousands" of ceasefire violations from Pakistan since the Modi government took over and growing incidents of Pak sponsored terror.
The party charged that the government's "flip-flop diplomacy is hurting the country dearly".
