The Foreign Ministry said police were on the scene.
Du, 57, left behind a wife and son who were not in Israel at the time of his passing due to COVID-19 restrictions on travel.
Police spokesman Micky Rosenfeld confirmed that Du was found in the early morning by the envoy's staff in his home in Herzliya.
Army Radio claims that the investigators have not found any signs of violence, which means that it is likely that Du passed from a heart attack.
