China's top political advisor Wang Yang on Sunday stressed implementing the work arrangements on Taiwan affairs made by the Communist Party of China Central Committee and upholding the principles of "peaceful reunification" and "One Country, Two Systems."

Wang, a member of the Standing Committee of the Political Bureau of the CPC Central Committee and chairman of the National Committee of the Chinese People's Political Consultative Conference, made the remarks at a conference on Taiwan affairs held in Beijing.

While reviewing the work on Taiwan affairs in 2019 and affirming positive progress made in the past year, Wang warned that the cross-Strait situation would be more complicated and grave in 2020.

He called for efforts to align thinking and actions with the decisions and work arrangements on Taiwan affairs made by the CPC Central Committee and emphasized the importance of upholding the one-China principle and resolutely opposing and deterring separatist activities for "Taiwan independence" in any form.

Wang also stressed the necessity of implementing targeted measures to improve the effects of policies beneficial to Taiwan compatriots, and advancing exchanges with youth across the Taiwan Strait to create better conditions for young people in Taiwan to study, start businesses or work on the mainland.
