KUNMING -- Police in Southwest China's Yunnan Province have caught one suspect and seized more than 45 kg of methamphetamine on the China-Myanmar border, authorities said Monday.

The man and drug were seized in Lincang City on Saturday morning, the border police with Lincang said in a statement.

The police received reports in early September that some people were planning to ship drugs to China from Myanmar. Then they set up checkpoints in key inspection areas.

On Saturday, three men carrying two woven bags crossed the border. They threw away the bags and ran back to Myanmar when seeing inspectors, the statement said.

One man was caught and another two fled. Police have found 23 packages of methamphetamine, or 45.17 kg in total.

Further investigation is under way.

Lincang is near Southeast Asia's Golden Triangle, a major area for opium production. By late July this year, police in Lincang had arrested 226 suspects in 422 cases and seized 1.025 tonnes of drugs.
