Chinese and Western observers seemed to reach a consensus on Wednesday over President Xi Jinping's proposal to establish a new framework for security cooperation in Asia, and he also sent a veiled warning to Washington.

"To beef up a military alliance targeting a third party is not conducive to regional common security," Xi said without mentioning the United States when delivering a keynote speech at a regional security forum in Shanghai on Wednesday.
