The Taiwan question is purely China's internal affair and brooks no external interference. We firmly oppose any form of military ties between US and China's Taiwan region, and urge the US side to abide by the one-China principle and the three China-US joint communiqués, prudently handle Taiwan-related issues, stop arms sales to Taiwan, and refrain from sending wrong signals to "Taiwan independence" separatist forces, Zhang Han, a spokesperson for the Taiwan Affairs Office of the State Council, said on Wednesday in response to a question regarding US dissatisfaction with Taiwan's arms procurement budget.
