Chinese President Xi Jinping on Thursday proposed a "global security initiative" that upholds the principle of "indivisible security," a concept also endorsed by Russia, although he gave no details of how it would be implemented.

During a video speech to the annual Boao Asia Forum, Xi said that the world should respect the sovereignty and territorial integrity of all countries, while paying attention to the "legitimate" security concerns of all.

"We should uphold the principle of indivisibility of security, build a balanced, effective and sustainable security architecture, and oppose the building of national security on the basis of insecurity in other countries," Xi told the gathering on the southern Chinese island of Hainan.
