Full coverage: Premier Li Attends UN Conferences, Visits Canada and Cuba

Chinese Premier Li Keqiang has spent the second day of his visit speaking about the world's poorest and talking to some of its richest.

The second summit in as many days on Refugees and Migration this time world leaders were asked to make financial pledges to help refugees resettle and make a new life.

"Not a single country, no matter how powerful and resourceful, cannot handle this one alone. The United Nations cannot handle this one alone. We need solidarity and we need unity in addressing this issue," UN chief Ban Ki-Moon said.

The meeting convened by outgoing U.S. President Obama heard him commit the U.S. to accept more refugees and China added to Monday's pledge of a 100 million dollars in refugee aid.

"At yesterday's meeting I pledged 100 million dollars to nations and organizations. Today, I will further promise that in the coming three years, through south-south cooperation assistance fund, China will provide 50 million dollars each year to multilateral humanitarian organizations and relevant UN initiations. China will also provide another 50 million dollars assistance each year through bilateral channels. In total, China pledged another 300 million dollars in new assistance," Chinese premier Li Keqiang said.

The global economy was on the agenda earlier as Chinese Premier Li met with former U.S. Treasury Secretary Hank Paulson and former New York Mayor, billionaire Mike Bloomberg.

Li Keqiang underlined the interdependence of the U.S. and Chinese economies.

"China and the United States not just have stable political ties, but also enjoyed very close business cooperation. I was told that on every second, each day, a Chinese is buying an iPhone product. And maybe when that Chinese customer is buying this iPhone, he is not aware that the real 'Big Apple' is New York City!" Li said.

And at The Economic Club of New York, Li Keqiang told an influential audience that the Chinese economy and Beijing's markets reforms are on track.

"Doctor Kissinger asked me if China's economic size equals that of the US…Per capital GDP of  the US is seven times that of China's per capital GDP," Li said.
