(CNN)Any suggestion that the departure of former US President Donald Trump from Washington would provide a temporary pause in US-China tensions has been swiftly dispelled.In the short time since President Joe Biden was sworn into office, China has flown more than two dozen combat aircraft near to the self-ruled island of Taiwan and passed a law allowing its coast guard to fire on foreign vessels. Meanwhile, the US Navy has sent an aircraft carrier strike group into the South China Sea.Analysts say such moves are likely only the beginning of what is expected to be a potentially uneasy initial relationship between the new Biden administration and Beijing.
