Peace, stability and development in cross-Strait relations is only possible by upholding the one-China principle and opposing "Taiwan independence," a mainland spokesperson said on Tuesday.
Ma Xiaoguang of the State Council's Taiwan Affairs Office made the remarks in response to a speech by the island's leader.
Ma reiterated the mainland's attitude and stressed that whatever propositions made by the island's authority, the key to cross-Strait relations is that Taiwan and the mainland belong to one China.
This year is the 30th anniversary of the opening of people-to-people communication across the Taiwan Strait.
The most important lesson from those 30 years is the fundamental role of the one-China principle, said Ma.
Only by upholding the one-China principle and opposing "Taiwan independence," can both sides promote communication and cooperation, said Ma.
