Former US national security adviser John Bolton on Friday reiterated a call for US naval visits to the Port of Kaohsiung, as he affirmed the Pentagon’s reported plan to send more troops to Taiwan.

The Wall Street Journal on Thursday reported that the US is increasing its small contingent of soldiers in Taiwan to train local forces.

The US military presence in Taiwan would grow from 100 to 200 troops, up from about 30 a year earlier, it said.
