Speaking in an interview with Chinese media on the sidelines of a forum on international affairs in China's southern city of Guangzhou, Ban said China's reform and opening-up has lifted hundreds of millions, both in China and elsewhere, out of poverty, xinhuanet.com reported.
"The World Bank announced proudly in 2010 that the number one goal of the UN Millennium Development Goals was achieved, if we look at the statistics internally, it is because of China," Ban said.
"China has also been contributing a lot to development issues," Ban said.
"This is highly commendable contribution.
"Now that you're beginning another forty years of reform and opening-up, I am quite confident that this will help greatly in implementing Sustainable Development Goals," he said.
"Again, number one goal of Sustainable Development Goals is to eradicate all the absolute poverty around the world."
The interview was conducted on the sidelines of the 2018 Imperial Springs International Forum, which gathered some 200 former world leaders, renowned scholars and business elites in Hangzhou for discussions on the theme of "Advancing Reform and Opening-up, Promoting Win-win cooperation."
The South Korean career diplomat, who served as UN secretary general from 2007 to 2016, also highlighted recent increasing challenges to multilateralism that had underpinned the world peace and prosperity over the past decades.
"The international peace, security and prosperity have been underpinned during last seven decades under the multilateralism systems, and multilateralism is now symbolized with the United Nations, and the United Nations Charter," Ban said.
Some countries are "not respecting multilateralism, which has been backbones of international society. This is really worrisome," he said.
