US officials have expressed concerns over escalation of tensions between China and Taiwan. In the recent day, repeated Chinese incursion into Taiwan has broken all previous records. What has irked China is probably the presence of US special operation forces in the island. According to reports, US forces and marines have been secretly training Taiwanese troops since 2020. Nearly 2 dozen US special forces had reportedly been training Taiwan’s ground and maritime forces ‘for at least a year’. According to sources, US service members have been present on the island even before Joe Biden took oath as President.
