Saudi Arabia - which is waging a war against Shiite Houthi rebels backed by its regional rival Iran - is the world's second largest importer of arms after India, SIPRI said.
Report by Stockholm International Peace Research Institute spotlights India's floundering attempts for make firearms in India and growing preference of U.S. over Russian Federation as arms supplier.
China is the fifth biggest arms supplier in the world and also supplies the most weapons to India's neighbours, a study by the Stockholm International Peace Research Institute has shown.
The world's arms sales in 2013-2017 increased by 10% compared to 2008-2012.
India continues its dubious standing as the largest importer of major arms in the world in 2013-17, accounting for 12 per cent of the global total.
"Most countries in the Middle East were directly involved in violent conflict in 2013-17, and arms imports by states in the region increased by 103 percent between 2008-12 and 2013-17", it said.
According to Siemon Wezeman, a senior researcher with the SIPRI Arms and Military Expenditure Programme, the tension in recent past with both Pakistan and China have led to the increase in growing demands of weapon, which India does not produce itself.
Despite its continuing tensions with India and ongoing internal conflicts, Pakistan's weapon imports decreased by 36% between 2008-12 and 2013-17.
"This development is part of the growing strategic partnership between the two countries under which the United States of America has begun to supply India with advanced military equipment", the report said. It supplied arms to as many as 98 states worldwide, accounting for more than a third of global exports.
Its latest report, titled "Asia and the Middle East lead rising trend in arms imports, USA exports grow significantly", highlights the most important trends in the current global arms industry.
The sale from United States arms majors, too, reduced by 76% between 2013 and 2017 compared to the previous five-year period.
However, the rise in arms import from the U.S. has been significant during the 2013-17 period. Despite this, it was the world's fifth largest arms importer in 2013-17. 'These deals and further major contracts signed in 2017 will ensure that the U.S. remains the largest arms exporter in the coming years'.
The Trump administration was nearing completion of a new "Buy American" plan that calls for US military attaches and diplomats to help drum up business for the USA weapons industry, according to media reports in January.
China's arms import slipped by 19 percent between 2008-12 and 2013-17 as the country produced its own advanced weapons.
Algeria accounted for 52 per cent of all African imports in 2013-17. The UK is the 6th greatest weapons exporter.
SIPRI, an independent institute, monitors arms deliveries by volume over periods of five years in order to iron out short-term fluctuations.
The SIPRI report notes deteriorating ties between the U.S. and Pakistan, stemming from the perception that Islamabad is not doing enough to combat terrorism in Afghanistan.
