Modi attended the G7 countries summit as special guest at the request of France. At these conferences, he met with Trump. Several issues were discussed during the meeting between the two. At a subsequent press conference, Modi responded to media queries in Hindi.
However, While Trump was addressing Modi said, Modi speaks fluent English, but he said he would speak Hindi in the Indian language with the intent of introducing the Indian language to everyone. Modi took Trump’s hand and shook hands.
We often find Modi prefers speak only in Hindi rather than any other languages. The intent may be anything but what what Trump has mentioned about this is something to be noted.
