James Thompson, the former chairman of AmCham who played a major part in organising Harbour Fest, said yesterday he would never apologise for an event he described as 'very successful'. He disagreed with conclusions of the independent panel's report into the event and said the American Chamber of Commerce had done its best and fulfilled its contract. 'We're proud of what we achieved,' he said, adding he would not organise a future Harbour Fest because he had suffered too much pressure. Financial Secretary Henry Tang Ying-yen said responsibility should not fall on a single official. He said AmCham should bear equal responsibility with government departments. The report attacked Mike Rowse, director-general of InvestHK, the department which oversaw Harbour Fest, for failing to properly monitor the event. 'The report's contents are very detailed, that is to say, not only the government departments but other organisations including AmCham had inadequacies and responsibility,' Mr Tang said. 'So I don't think Mike Rowse is the only one to take responsibility.' He said both the government's Economic Relaunch Working Group and AmCham had 'underestimated the complexity of organising the Harbour Fest and we have overestimated its benefits'. 'In many respects, we all could have done better,' said Mr Tang. 'Because of these factors, Harbour Fest could not have obtained the results we set out to achieve. We express our deepest disappointment [and] our regret. We will certainly learn from the experience.' Mr Rowse stood behind Mr Tang yesterday and refused to speak after the two attended a short briefing on the report.
