Du Wei previously hit out at criticism of his country's handling of the coronavirus pandemic
China's ambassador to Israel, Du Wei, was found dead at his residence on the outskirts of Tel Aviv on Sunday, police said.
Du Wei became ambassador to Israel in February, and previously hit out at criticism of his country's handling of the coronavirus pandemic.
The 57-year-old envoy was found dead in his home in Herzliya, north of the city, spokesman Micky Rosenfeld told AFP, adding that police were investigating.
Du's wife and son were not with him in Israel.
His death comes just two days after he condemned comments made by US Secretary of State Mike Pompeo made during a visit to Israel.
Pompeo denounced Chinese investments in Israel and accused China of hiding information about the coronavirus outbreak.
But Du told Haaretz: “China is a law-abiding, responsible country, and should be trusted.
"Different things have been said regarding China's battle [against the coronavirus]. Initially, some were condescending and gloating.
“When the disease broke out across the world, there were those who said that China has to apologize. They were looking for a scapegoat.
"Throughout history, certain groups of people have been accused with spreading plagues more than once. "It's despicable and should be condemned. The disease is the enemy of the entire mankind, and the world should fight it together.”
Israeli police and forensics teams could be seen at the residence, a property guarded by a low wall and shaded by a leafy garden, AFP reporters said.
The Chinese foreign ministry said it would only comment when it had "solid" information.
Du had previously served as ambassador to Ukraine, according to his biography on the embassy's website.
The Haaretz daily said initial reports said staff had found Du dead in his bed and that there were no signs of violence.
It quoted Israel's emergency medical service Magen David Adom as saying the cause of death appeared to be a cardiac incident.
Du had undergone a 14-day home quarantine on arrival in Israel because of the new coronavirus outbreak, according to an interview with local media in May.
