TAIPING ISLAND — Taiwan flew international media to its largest island holding in the South China Sea on Wednesday in a bid to reinforce its territorial claims in the disputed and increasingly tense region. Two dozen journalists were flown to the island aboard a Taiwanese air force C-130 transport plane that landed on an airstrip guarded by coast guard sentries with rifles. Speaking to reporters in Taipei following the trip, Taiwanese President Ma Ying-jeou said he would invite Philippine government representatives, lawyers, and five members of the arbitration commission to visit Taiping themselves to see that it is “an island with fresh water, capable of sustaining farm production, livestock and human life.” Taiwan, which lacks diplomatic ties to negotiate with the five other governments with territorial claims in the South China Sea, has increasingly turned to public diplomacy to reinforce its own claims.
