World Trade Organization on 24 February 2016 ruled in favour of the United States. It had challenged New Delhi's discrimination against US solar exports.

• The panel agreed with the US that India's localisation rules discriminated against imported solar cells.

• The US Trade Representative's office termed the ruling a significant victory that will fasten the spread of solar energy across the world.

• In 2013, the US launched a dispute against India at the WTO.

• It complained that its DCR measures violated core norms of trade-related investment provisions

• The US argued that the rules are a barrier to solar products made in America

The US said that its solar exports to India had fallen by 90 per cent from 2011, after India imposed the rules.
