Nine athletes of host Indonesia secured final spots at the 14th pencak silat world championships after a tight semifinal Wednesday, a media reported here on Thursday. The Championships has started since Sunday in Jakarta and will end on Friday. 'We also aim for golds in the arts event,' Indonesian team manager Edi Prabowo was quoted by the Jakarta Post as saying here. Indonesia had 15 fighters in the semifinals round. However, six of them failed to progress to the finals. Separately, team Thailand withdrew from the championship because it felt it was being treated unfairly by referees when it faced Malaysia in the quarterfinals Tuesday. The championship is participated by athletes from Indonesia, Vietnam, Thailand, Malaysia and Brunei Darussalam.
