Tea Board Chairman Lalith Hettiarachchi, who was chief guest at the AGM, said the industry should not become complacent in its position as one of the world's top tea exporters.
Although the island's tea is renowned for its purity and quality, he noted that these are "relative terms".
Consumers were now demanding more and more stringent standards as they get better educated, Hettiarachchi said,
