The Taiwanese troops have been monitoring the situation and have ordered air, sea and land units to respond to China's activities near the island, the statement read.
Taiwan is holding general elections on Saturday. The three candidates running for head of the administration of the island are Lai Ching-te of the ruling Democratic Progressive Party (DPP) who is a pro-independence candidate, Hou Yu-ih of the main opposition Kuomintang party who supports gradual resumption of dialogue with China, and Ko Wen-je of the Taiwan People's Party who is also ready for contacts with Beijing. Taiwan's regional leader is elected by a simple majority of votes for a four-year term.
Voters are also to elect 113 members of local legislature also by a simple majority of votes for four-year terms.
Taiwan has been governed independently from mainland China since 1949, but Beijing views the island as part of its sovereign territory. Taiwan's outgoing DPP-led administration has been largely perceived as pro-independence, chiefly due to its frequent contacts with US officials and international activism, which prompted Beijing to ramp up military drills in the Taiwan Strait in recent years.
