BEIJING, June 10 (Xinhua) -- China expressed deep condolences over the passing of Burundian President Pierre Nkurunziza, a Foreign Ministry spokesperson said Wednesday.

President Nkurunziza died of a heart attack in a hospital in east-central Burundi, according to a Burundian government statement issued on Tuesday.

"China expresses its deep condolences and sincere sympathies to the government and people of Burundi and the family of President Nkurunziza," Hua told a press briefing.

Nkurunziza was also a good friend to the Chinese people as he was devoted to the cause of China-Burundi friendship and contributed greatly to deepening bilateral all-weather partnership, Hua said.
