Prime Minister Manmohan Singh on Friday left for home wrapping up his two-nation tour of US and Brazil during which he attended the Nuclear Security, IBSA and BRIC summits besides meeting a number of world leaders, including US President Barack Obama.
With ash cloud from Iceland's erupting volcano creating havoc for flights in northern Europe, Singh is taking a detour on way back from Brasilia, avoiding Frankfurt for a stopover.
Singh's special aircraft will now have a stopover in Johannesburg, South Africa. He will reach home Saturday afternoon.
During the first leg of his 8-day tour, the Prime Minister was in the US for four days during which he attended the Nuclear Security Summit and met Obama and asked him to press Pakistan to rein in LeT and other terror outfits targeting India.
The Prime Minister, who held a 50-minute meeting with Obama on last Sunday, emphasised that Pakistan needed to take "convincing action" against those responsible for Mumbai attacks.
During the talks, Singh also secured an assurance from Obama for access to India to Pakistani-American terrorist David Coleman Headley, who has confessed to plotting Mumbai attacks.
At the Summit, Singh warned of dangers posed by nuclear explosives falling into the hands of non-state actors posing danger to India and other countries.
With Pakistan obviously on his mind, he pitched for "zero tolerance" against individuals and groups which engage in illegal trafficking of atomic explosives and announced at the summit India's decision to set up a 'Global Centre for Nuclear Energy Partnership'.
After the US visit, Singh arrived in Brasilia on a 3-day visit to attend the India-Brazil-South Africa and Brazil-Russia-India-China Summits.
In Brasilia, besides attending IBSA and BRIC summits, he held bilateral meetings with Chinese President Hu Jintao and Russian President Dmitry Medvedev and discussed various issues with them.
At the IBSA Summit, Singh pitched for greater focus on investments in infrastructure and inclusive growth to create new sources of growth.
He also said the group of leading developing economies must speak against the protectionist policies "which are only short-sighted and self-defeating in the long run."
At the BRIC Summit, Singh pitched for a close cooperation among the four countries in the fields of energy and food security besides tapping potential in other sectors like trade and investment, science and technology and infrastructure.
