See pic: When Prime Minister of Singapore visited Facebook Headquarters!

Facebook is the biggest social media platform in the world that reaches out to various parts of the world and endeavours to connect people globally.

With over 1.44 billion monthly active users, as of March 2015, Mark Zuckerberg has succeeded in putting Facebook on the global map.

This said, the world's leaders look forward to visit the social media headquarters in the United States to reach out to the global audience and connect with them. This is not saying much, considering that the said leaders themeselves are Facebook users.

Prime Minister of India, Mr Narendra Modi also visited Facebook recently, in September, 2015. Now, the Prime Minister of Singapore, Mr Lee Hsien Loong, became the newest addition to Zuckerberg's list of “World leaders who visited Facebook”.

Mark Zuckerberg shared his proud moment with the world through a photograph, which he captioned saying, “It was an honor to host Prime Minister Lee Hsien Loong of Singapore at Facebook HQ today.

The Prime Minister is one of the only world leaders who knows how to code. To recognize his technical skills, we gave the PM this artwork designed at Facebook etched with lines from a computer program he wrote. Coding can be useful -- no matter what your job is!”

Barack Obama, Narendra Modi have strong, productive relationship, says US official

Washington: US President Barack Obama and Prime Minister Narendra Modi have developed a strong and productive relationship between them, a top American climate change official has said.

"President Obama and Prime Minister Modi have a very, strong and productive relationship, not just on climate change but broadly," Todd Stern, the US Special Envoy on Climate Change said on Tuesday.

"It was a quite extraordinary fact that within the space of four months there were two head of the state visits, one first to the United States in September of 2014 and then Prime Minister Modi invited the President to India just four months later in January," the official said.

Thereafter the two leaders have been close communications with each other. "They met on the margins of the UNGA in New York and they met on the first day of the Paris meeting," Stern said.

According to Stern the meeting was a very warm and positive, cordial and detailed.

"In fact, they talked so long that they were both supposed to go — and did go finally, but they were a little bit late to the announcement of this big Mission Innovation idea on R&D that both — well, the United States, India, China, many other countries ultimately were part of," the US official said.

"So I think, that the call later, sort of more towards the end, was a check-in call to see how we were doing and to urge us all on together toward a successful conclusion. And I think it was done in that spirit, not in the spirit that there was some specific thing that had to be done before the agreement could get completed," Stern said.
