Chinese President Xi Jinping on Sunday vowed to deepen reform and opening up across the board as he gave his New Year address to ring in 2024.

Xi called for the further enhancement of people's confidence in development, promotion of the vibrant development of the economy, and a redoubling of efforts to boost education, advance science and technology, and cultivate talents.

"We will continue to support Hong Kong and Macao in harnessing their distinctive strengths, better integrating themselves into China's overall development, and securing long-term prosperity and stability," Xi said.

"China will surely be reunified," Xi stressed, adding that all Chinese people on both sides of the Taiwan Strait should be bound by a common sense of purpose and share in the glory of the rejuvenation of the Chinese nation.
