China is stepping up pressure on self-ruled Taiwan a month ahead of the inauguration of a president from a pro-independence party Beijing distrusts, signaling a rocky start for the leader of the island elected on a wave of anti-China sentiment.

In the past few weeks, China has established ties with former Taiwan ally Gambia, sent a top general to inspect troops based in a frontline province and scooped up dozens of Taiwanese from Kenya wanted in China for fraud — a move denounced by Taipei as being more about politics than crime.

And Taiwan said a hotline meant to expedite direct communication between the top government officials dealing with each other's affairs had not been answered by China twice at critical times of late.
