Taiwan President Tsai Ing-wen visited a low-key but critical maintenance base for fighter jet engines on Saturday, offering encouragement as the Chinese-claimed island's armed forces strain in the face of repeated Chinese air force incursions.
This month alone, China's drills have included its jets crossing the mid-line of the sensitive Taiwan Strait and exercising near the Taiwan-controlled Pratas Islands in the South China Sea.
Beijing regards Taiwan as a wayward province and has never renounced the use of force to bring the democratic island under its control.
