China and Taiwan have added tourism to their bones of contention since the pro-independence opposition swept to power in January elections, trading accusations about who is to blame for a decline in Chinese visitors to the self-ruled island.
China has made no secret of its dislike for incoming President Tsai Ing-wen, who takes office on May 20, and for her Democratic Progressive Party, which has traditionally favoured independence.
Since the polls, Taiwan has accused China of effectively kidnapping its citizens from Kenya on suspicion of involvement in fraud, and reacted angrily to China casting doubt on its observer status at the World Health Organization.
