Xi Jinping, general secretary of the Communist Party of China (CPC) Central Committee, said the initiative of building a community with a shared future for mankind is being transformed from a concept into action.

Xi made the remarks while delivering a speech on Friday at the opening ceremony of CPC in Dialogue with World Political Parties High-Level Meeting in Beijing.

"I'm delighted to see that the friendly cooperation between China and other countries is increasingly expanding and the concept of a community with a shared future for mankind is gaining support and endorsement from an increasing number of people," Xi said.

The concept of building a community with a shared future for mankind was put forth by Xi in 2013.

The Belt and Road Initiative is the practice of the concept, Xi said, adding the Belt and Road has become a huge cooperation platform for countries concerned to realize their common development.

Proposed by Xi in 2013, the Belt and Road Initiative aims to build trade and infrastructure networks connecting Asia with Europe and Africa via land and maritime routes.

In his speech, Xi said building a community with a shared future for mankind is in essence to connect the prospects and destinies of every nation and country closely together, share weal and woe, and turn planet Earth into a harmonious family.

He said efforts shall be made to build a safe world free of fear, adding a country cannot gain its security at the cost of others'. Threats facing other countries may be challenges to ourselves.

"Facing increasingly complicated and integrated threats, we shall not fight alone, nor shall we worship military force," he said, adding all countries should pursue a new security concept featuring common, comprehensive, cooperative and sustainable development.

All countries should create fair, just and shared security to jointly eliminate the root cause of war and rescue people from pains brought about by war, he said.

In the meantime, countries should also strive to eliminate poverty and promote common prosperity, Xi said, citing challenges such as the North-South development imbalances, poverty, hunger and digital gaps.

The old-school winner-takes-all mentality and beggar-thy-neighbor approach would not only block the doors of others, but also barricade one's own path. "They would erode a country's own roots for growth, and impair the future of whole humanity," he said.

He said the world should push forward open, inclusive, beneficial, balanced, and win-win economic globalization, to deliver benefits to all countries and create comfortable lives for children worldwide.

Xi went on to emphasize the significance of an open and inclusive world, urging the world to break cultural barriers and let all kinds of civilizations exist and grow in harmony.

Stressing the building of a clean and beautiful world with picturesque scenery, Xi called for efforts to ensure coexistence between man and nature, cherish the environment as we cherish our own lives, respect and protect nature, and safeguard the irreplaceable planet Earth.
