A German engineer who flew to China on a special charter flight Saturday has tested positive for the coronavirus.

The Tianjin city government said in a social media post that the 34-year-old man from Blaustein, Germany, had a body temperature of 36.3 Celsius (97.3 Fahrenheit) and no COVID-19 symptoms. It did not give his name. He has been transferred to a hospital where he will be kept for medical observation.

About 200 people arrived on the chartered Lufthansa A340 from Frankfurt. A second flight is scheduled to depart on Wednesday for Shanghai.

China has banned most foreigners from entering the country to try to prevent the introduction of new infections, but agreed to allow the two German flights to bring back businesspeople as it tries to revive economic growth after the coronavirus shutdowns.
