China will import more goods and services, ease market access for foreign investment and step up intellectual property protection amid the country's efforts to boost openness, President Xi Jinping said Thursday.

"With these efforts, we will break new ground in pursuing all-dimensional, multitiered and all-sector opening-up in China," Xi said in a speech at the 11th BRICS summit in Brasilia.

The five BRICS members — Brazil, Russia, India, China and South Africa — should undertake their due obligations in practicing multilateralism at a time when crucial developments are taking place in the world economy, Xi said.

The president pointed out that the world is facing various challenges, including the rise of protectionism and unilateralism; a greater deficit of governance, development and trust; and growing uncertainties and destabilizing factors in the world economy.

A new round of technological revolution and industrial transformation is ascendant, and the unstoppable rise of emerging markets and developing countries has injected a strong impetus into the reform of the global economic governance system, Xi said.

Faced with profound changes rarely seen in a century, major emerging markets should grasp the trend of the times, respond to the call of the people, and strengthen cooperation for the well-being of the people and for the development of the world, Xi said.

Xi called on the BRICS countries to work together to foster a security environment of peace and stability, saying that the five members should safeguard peace and development for all, uphold fairness and justice, and promote win-win results.

The BRICS members should uphold the principles of the United Nations Charter, oppose hegemonism and power politics, and take a constructive part in settling geopolitical flash points, he said.

The BRICS countries should also maintain close strategic communication and coordination and speak in one voice for a more just and equitable international order, he added.

Xi proposed the BRICS countries pursue greater development through openness and innovation.

The five-member group should strive for more productive cooperation in fields such as trade and investment, digital economy and connectivity, so as to achieve high-quality development, Xi said.

He called for the five countries to advocate extensive consultation, joint contribution and shared benefits in global governance and push for reform of the global economic governance system.

The BRICS countries should stand firm against protectionism, uphold the WTO-centered multilateral trading system and increase the voice and influence of developing countries in international affairs, Xi said.

The BRICS countries should promote mutual learning through people-to-people exchanges and take those exchanges to greater depth, Xi said.

China will continue to act in the principle of extensive consultation, joint contribution and shared benefits, and pursue open, green and clean cooperation within the framework of the Belt and Road Initiative, Xi said.

"We will continue to follow a high-standard, people-centered and sustainable approach to promote high-quality Belt and Road cooperation with partner countries," he said.

China is committed to working with Africa for an even stronger China-Africa community with a shared future, Xi said, adding that China will pursue closer cooperation with Latin America and the Caribbean in various areas and build a China-LAC community with a shared future.

China strives for an Asia-Pacific community with a shared future that features openness and inclusiveness, innovation-driven growth, greater connectivity and mutually beneficial cooperation, Xi said.

"All in all, China will work with the rest of the international community toward the goal of building a new type of international relationship and of building a community with a shared future for mankind," he said.

Brazilian President Jair Bolsonaro, Russian President Vladimir Putin, South African President Cyril Ramaphosa and India's Prime Minister Narendra Modi also delivered speeches during the meeting.

After the BRICS leaders' session, the five leaders had a dialogue with the BRICS Business Council and the New Development Bank, a multilateral development bank established by the BRICS states.
