New Delhi, Aug. 27 -- Prime Minister Narendra Modi refused to take at least four phone calls from US President Donald Trump recently, German newspaper Frankfurter Allgemeine Zeitung (FAZ) has reported.

This comes against the backdrop of the row over US tariffs levied on India.

FAZ, which has examined the ongoing India-US tariff dispute, also said that President Trump's usual methods in trade conflicts - complaints, threats, and pressure - were not working in India's case as they have with other countries.

"There are signs indicating that Modi felt insulted," FAZ claimed, adding that Modi's refusal to speak to Trump demonstrates the depth of his irritation and his caution.
