The political and legal statuses of Taiwan are contentious issues. The People's Republic of China (PRC) claims that the Republic of China government is illegitimate, referring to it as the "Taiwan Authority". The ROC has its own currency, widely accepted passport, postage stamps, internet TLD, armed forces and constitution with an independently elected president. It has not formally renounced its claim to the mainland, but ROC government publications have increasingly downplayed this historical claim.
