New Delhi is prepared to include a sweetener in trade talks with Washington that would "future-proof" a deal by ensuring no other trade partners could have superior terms, as it pushes for a quick agreement with the Trump administration, Indian government officials said. The "forward most-favoured-nation" clause, rarely granted by India in previous trade negotiations, would automatically apply to the U.S. any more-favourable tariff arrangements that might be agreed with other countries, two officials with direct knowledge of the matter told Reuters.
