Soyabean milk producer Vitasoy International Holdings is sticking to its original sales target for the mainland despite a 22.8 per cent drop in sales in the six months to September. The company, which aims to raise mainland sales to 20 per cent of turnover in five years from 6 per cent, said the fall was due to increased selling prices, caused by the introduction of glass-bottle recycling in southern China. The firm raised prices for soft-pack soyabean drinks in eastern China to maintain price levels. The measures affected sales despite being marked as a future growth driver in the price-sensitive mainland market. Revenue from mainland sales slid 22.8 per cent year on year to $71 million in the first six months. Operating profit rose 35.32 per cent to $38.27 million. Executive chairman Winston Lo Yau-lai said the firm would justify the higher selling price by focusing on brand building. 'We will maintain our original mainland sales target because the sales decline is narrowing now,' Mr Lo said. The firm posted a 26.17 per cent gain in net profit to $67.91 million for the six months to September. Turnover rose 7.95 per cent to $1.23 billion.
