Chinese President Xi Jinping delivered a speech via video at the opening ceremony of the 2021 Understanding China Conference in Guangzhou, south China's Guangdong Province on Thursday.

Our world is experiencing changes unseen in a century, said Xi, stressing that it is all the more important for us to exchange views, have more interactions and cooperation, and contribute our wisdom and strength to jointly address global challenges.

"To understand China today, one must learn to understand the Communist Party of China (CPC)," Xi said in his address.
