New Delhi, July 2 -- Prime Minister Narendra Modi will begin his eight-day, five-nation tour today. During the tour - his longest foreign trip in ten years - the prime minister will participate in the crucial BRICS Summit in Brazil and expand India's ties with several key nations of the Global South.

The PM's trip will cover two continents and include visits to Ghana, Trinidad and Tobago, Argentina, Brazil, and Namibia.

PM Modi's last eight-day trip was to six nations in July 2015 when he visited Russia and five Central Asian countries. Officials said the tour will focus on defence, rare earth minerals, and cooperation on counter-terror measures, among other issues.
