The latest manufactured angst in the United States about the president's phone habits is yet another demonstration of the zero-sum Cold War mentality that still grips Washington, a China Daily editorial said.

Peace, development and win-win cooperation are the trends of today's world, and the future of people around the world is closely connected, according to President Xi Jinping, in his congratulatory letter to the eighth Beijing Xiangshan Forum.

The forum, themed "Building a New Type of Security Partnership of Equality, Mutual Trust and Win-Win Cooperation", which Xi praised for playing a positive role in promoting security dialogue, mutual trust and cooperation in the Asia-Pacific region since its launch eight years ago, is part of China's continuous endeavors to deepen global mutual trust, build consensus, mitigate suspicion and expand cooperation.

Those denying the validity of agreements and global institutions are seeking to destroy the underpinnings of global stability that support the trend for multilateral cooperation.

The practice of seeking exclusive security at the expense of others' legitimate interests and concerns is no longer desirable, or indeed tolerable. Those clinging to the ways of the past will be left behind by history.
