Indian national Kulbhushan Jadhav was granted second consular access on Thursday, Pakistan media reported.
Indian officials are presently at Pakistan Foreign Office.
Earlier, New Delhi had asked Islamabad to give "unconditional consular access" to Jadhav, as per sources.
"Last time what they did was insulting to his mother, father and wife and insulting to India as a whole. So we want that consular access should be unconditional," Arvind Singh, Kulbhushan Jadhav's childhood friend, told ANI.
Earlier, Ministry of External Affairs of India said that Pakistan coerced Kulbushan Jadhav to forego his rights to seek implementation of judgment of International Court of Justice.
MEA's statement came after Pakistan claimed that Kulbushan had refused to file a review plea for reconsideration of his sentence and conviction.
MEA further added that Pakistan's claim that Kulbushan Jadhav refused to initiate review petition is a continuation of farce.
"Kulbushan Jadhav sentenced to execution through a farcical trial. He was coerced to refuse to file review in his case," MEA said.
The Ministry also said that India sought unimpeded access to Jadhav to discuss his remedies and despite repeated requests, Pakistan continues to deny India free and unimpeded access to Kulbushan Jadhav, MEA said.
Further, MEA said, "Clearly, Pakistan is attempting to create a mirage of compliance with ICJ judgement in the case" and added that Pakistan refused to hand over any relevant document, including FIR, evidence, court order related to the case to India.
"ICJ has already held that Pakistan is in egregious violation of international law. Government will do its utmost to protect Jadhav and ensure his safe return to India. To that end, it would consider all appropriate options," added MEA.
Pakistan claims that Jadhav was arrested from Balochistan in 2016 on charges of espionage. India has rejected Pakistan's allegations about Jadhav's involvement in spying and subversive activities and said he was kidnapped from the Iranian port of Chabahar.
In early 2017, a Pakistani military court sentenced him to death. In May 2017, the International Court of Justice (ICJ) stayed his execution.
In July last year, the ICJ, by a vote of 15-1, had upheld India's claim that Pakistan has committed an egregious violation of the Vienna Convention on Consular Relations on several counts.
