INTERFORM Ceramics Technologies is to set up a training centre in southern China next year to meet its growing need of skilled workers for its ceramics factories. Chairman Ngan Man-po said the centre, which would train about 600 machine operators annually and between 100 and 200 workers for retail warehouse operations, would be headed by Japanese and mainland instructors. China, he said, would double its ceramics production between 1995 and 2000, with output 80 per cent for the mainland market and 20 per cent for exports. Interform, which plans to export table-ware to Hong Kong and the United States, also was studying Africa as a new market. Mr Ngan said Interform, which handled a great deal of Hong Kong Government business, planned to increase its penetration of the private sector.
