India will urge its airlines not to take part in the European Union Emissions Trading Scheme (ETS), a senior official said, the latest salvo in an escalating row over an EU law requiring all flights in and out of Europe to pay for their emissions.

China in February said its airlines were barred from participating in the scheme unless they get government approval to do so. Beijing has also suspended the purchase of $14 billion worth of planes for Europe's Airbus due to the dispute.
