TIANJIN, Sept. 1 (Xinhua) -- Chinese President Xi Jinping on Monday proposed the Global Governance Initiative (GGI), calling on countries to work in concert for a more just and equitable global governance system.

Xi made the remarks when chairing the "Shanghai Cooperation Organization (SCO) Plus" Meeting in north China's port city of Tianjin, where the SCO held the largest summit in its 24-year history, attended by leaders from more than 20 countries and heads of 10 international organizations.

The GGI marks the fourth landmark global initiative proposed by Xi over the past several years, following the Global Development Initiative, the Global Security Initiative and the Global Civilization Initiative.

Xi highlighted five principles of the GGI -- adhering to sovereign equality, abiding by international rule of law, practicing multilateralism, advocating the people-centered approach, and focusing on taking real actions.
