Taiwan has a population of roughly 23 million people

The military released a statement to say it had acted in response to unspecified "provocation" from the democratically-governed island and the United States.
Taiwan, which China claims as its own territory, has complained of repeated Chinese military activity nearby over the past three years or so as Beijing seeks to pressure Taipei to accept Chinese sovereignty.
China staged war games around Taiwan in August following a visit to Taipei by then-US House Speaker Nancy Pelosi, and on Saturday it condemned the United States for a new defence authorisation law that boosts military assistance for Taiwan.
"This is a resolute response to the current escalation of collusion and provocation from the United States and Taiwan," it added, without giving details.
"Theatre forces will take all necessary measures to resolutely defend national sovereignty and territorial integrity."
Taiwan's defence ministry declined immediate comment.
The ministry publishes a daily report at 9am local time (1am GMT) of Chinese military activities near the island over the previous 24 hours.
The United States is Taiwan's most important international backer and arms supplier, despite the absence of formal diplomatic ties. US arms sales to Taiwan are a constant irritant in Beijing's relations with Washington.
Taiwan's military is dwarfed by that of its huge neighbour China. Its air force in particular has come under strain from having to scramble repeatedly to see off Chinese incursions near the island over the past three years or so.
The Chinese drills coincided with newly elected city mayors and county chiefs in Taiwan taking up their positions following local elections on the island last month, in which the ruling Democratic Progressive Party was trounced.
China has never renounced using force to bring Taiwan under its control. Taiwan strongly disputes China's sovereignty claims, saying only the island's 23 million people can decide their future.
