HONG Kong's re-export trade is expected to slow as markets for Chinese-made products in developed economies mature. Re-exports in the first 11-months of 1993 grew 20 per cent to $749.45 billion over the same period in 1992, according to detailed figures released by the Census and Statistics Department yesterday. Re-exports grew 14 per cent to $72.35 billion in November over the same period in 1992. While the figures showed healthy growth of the territory's re-export trade, Peregrine Brokerage senior economist Vincent Chan said its pace was slowing. ''You cannot expect re-exports to continue to grow at the pace of the past two to three years of between 40 and 50 per cent,'' he said. ''It is now more likely to grow at the pace of approximately 20 per cent.'' The slowdown was attributed to the saturation of the markets for Chinese-made products in its major markets, especially in the US. As Hong Kong's trade in re-exports in the past has been predominantly driven by re-export of Chinese products, a wind-down was expected. In the long term, said Mr Chan, Hong Kong's trade would be driven by trade in services. China was Hong Kong's biggest market for its re-exported goods in dollar terms, rising 15.4 per cent to $23.81 billion on a month-on-month basis. , and 30.9 per cent to $248.24 billion on year-on-year basis. It was followed by the US and Japan.
