Taiwan (traditional Chinese: 臺灣/台灣; simplified Chinese: 台湾; pinyin: Táiwān), officially the Republic of China (ROC), is a country in East Asia. Neighbouring countries include the People's Republic of China (PRC) to the northwest, Japan to the northeast, and the Philippines to the south.
At the end of the Chinese civil war, the government of China retreated to Taiwan, which they call the Republic of China. The communist regime in the Chinese Republic refuse to recognise Taiwan as a separate country. Hence Cena apologising to his Chinese fans.
