President Xi Jinping on Wednesday said the Taiwan question is China's internal affairs and allows no external interference.
Xi, also general secretary of the Communist Party of China Central Committee and chairman of the Central Military Commission, made the remarks at a gathering in Beijing to commemorate the 40th anniversary of issuing Message to Compatriots in Taiwan.
The Chinese people's affairs should be decided by the Chinese people, Xi said, stressing that the Taiwan question concerns China's core interests and the national bond of the Chinese people.
China's reunification does not harm any country's legitimate interests, including their economic interests in Taiwan, Xi said.
It will only bring more development opportunities to other countries, inject more positive energy into the prosperity and stability in the Asia-Pacific region and the world, and make greater contributions to building a community with a shared future for humanity, to world peace and development, and to the cause of human progress, he added.
