The United States said it was taking action at the world trade organization against Indian government export subsidies, which officials say as unfairly disadvantaged American workers and the manufacturers.

The U.S. Trade representative Robert Lighthizer in a statement said the export subsidy programs harm American workers by creating an uneven playing field on which they must compete.

Lighthizer said “USTR” would continue to hold its trading partners accountable by vigorously enforcing US rights under its trade agreements and by promoting fair and reciprocal trade through all available tools, including the WTO.

According to Lighthizer’s office, India offers benefits valued at $7 billion annually to domestic exporters such as duty, tax and fee exemptions — including producers of steel, pharmaceuticals, chemicals, information technology products and textiles.

The action opened a new front in President Donald Trump’s intensifying trade offensive, with the White House having already announced import duties on steel and aluminum as well as imports of solar panels and washing machines.
