Mukherjee also laughed away Belgian King Philippe's description of him as a "consensus builder in India" and said there was "nothing to read in between" the remark.
"What King Philippe meant was my (earlier) role in being the leader of the coalition in the House ( Lok Sabha) and nothing more than that," he said when he was asked if the monarch's words referred to the role he might play after the 2014 general election.
Mukherjee today reached Turkey, the second leg of his tour, after a four-day visit to Belgium where he attended a host of state events and held talks with top leaders.
Mukherjee lauded Belgium for supporting India's efforts to secure civil nuclear cooperation.
"Belgium has certain specialisations. Belgium's cooperation (is) asserted by the fact that it was one of the first countries which extended its cooperation after India signed the civil nuclear agreement with the US," he said.
Belgium was also one of the first countries to extend cooperation when India sought a waiver from the Nuclear Suppliers Group to commence civilian nuclear trade, he noted.
"Therefore, it will be useful in cooperation in managing nuclear waste, which is a major problem for all nuclear power countries," he said.
