China vows to defend sovereignty, territorial integrity as Taiwan's Lai arrives in Marshall Islands

China has vowed to defend its "national sovereignty" and "territorial integrity", as Taiwanese President William Lai sets foot on the Marshall Islands on the second stop of his Pacific tour. In a speech to the Marshallese parliament, Mr Lai announced the provision of a "preferential loan" for state-owned Air Marshall Islands to buy new aircraft. The Marshall Islands is among a dozen nations that have retained relations with Taipei, which has lost a string of diplomatic allies to China in the last few years. Victoria Jen reports from Taipei.
