Economic growth for the rest of the year will be worse than the first six months, Government economist Tang Kwong-yiu predicted yesterday. Mr Tang said growth for the second quarter was the lowest since 1974. He said that he expected gross domestic product figures to worsen in the coming months. However, he refused to acknowledge the predicted 4 per cent economic growth shrinkage reflected the real picture. He said: 'Usually economic activities will increase in the second half of a year.' Mr Tang said he had not reached a conclusion on whether next year's GDP would be negative. Since the air cargo handling at the new airport had returned to normal, the adverse effect of the initial breakdown of the service on GDP was expected to be less than 0.35 per cent, he said.
