JINAN, July 7 (Xinhua) -- Scientists are expected to have a "decisive outcome" on search for the source of dark matter by 2024 after analyzing the huge amount of data on cosmic particles, said Nobel Prize winner Samuel Ting Saturday.

The white paper, however, noted that the Plateau still faces many ecological challenges, including glacier retreat, melting permafrost, and other growing disaster risks due to global warming, and prominent contradictions between protection and development in the course of economic growth.

They said that the EU was willing to expand cooperation with China and step up communication and coordination with China in international affairs.

As the world economy is going through profound transition and changes, only by opening themselves can different countries achieve mutual benefit, shared prosperity and sustainable development. This should be the right choice for all countries. We BRICS countries should firmly promote an open world economy, be resolute in rejecting unilateralism and protectionism, promote trade and investment liberalization and facilitation, and jointly steer the global economy toward greater openness, inclusiveness, balanced growth and win-win outcomes for all. We should ensure that economic globalization will deliver more benefits. We should help emerging markets and developing countries, African countries and the least developed countries in particular, fully involve themselves in international division of labor and share in the benefits of economic globalization.
