India has world's "worst" tariffs on US products: Senator Graham

India is "the worst" in terms of high tariffs on American products, a top American Senator claimed on Sunday, ahead of US President Donald Trump's crucial meeting with Prime Minister Narendra on the sidelines of the G-7 Summit in France which is likely to be dominated by trade frictions between the two countries.

President Trump, championing his 'America First' policy has been a vocal critic of India for levying "tremendously high" duties on US products, has described the country as a "tariff king".

"When you look at the world tariff regime; 67 per cent of all the tariffs in the world disadvantage America. There's a higher tariff on American products in the country in which we do business with. India is the worst," Senator Lindsay Graham told CBS.

Graham, over the past several months has emerged as a close confidant of Trump on issues related to South Asia.

He was present when Trump held meeting with the visiting Pakistani Prime Minister Imran Khan at the White House last month.

Responding to a question, the Senator from South Carolina said he had introduced a bill in the Senate that allows the American President to charge a country the same as it does with the US while doing business.

"So, like in India... they have a 100 per cent tariff on a lot of our products. Either we increase tariffs on Indian products, or we all go to zero. The goal is to go to zero," Graham said.

The Trump-Modi meeting assumes significance in the wake of the strain that has popped up in the bilateral relationship on a host of trade and economic issues.

Ahead of the meeting in France on the sidelines of the G-7 summit, the White House said that trade and tariffs would be important topics of discussion between the two leaders.

"They will look for solutions on the trade front. The US is looking to India to reduce tariffs and open its markets," a senior administration official said, ahead of the meeting early this week.

Early this week, India's Ambassador to the US Harsh Vardhan Shringla had met Graham at the US Capitol.

According to the Indian Embassy, they "discussed the immense potential for closer strategic and economic ties between the world's oldest and largest democracies."
