Xiao also downplayed worries over Yang’s health on Monday and said it was not as grave as described by his family, although it was “not perfect”.
A pro-democracy blogger and spy novelist, Yang is an Australian citizen born in China who was working in New York before his arrest at the Guangzhou airport in 2019.
A Beijing court last month handed him a suspended death sentence on espionage charges, shocking his family and supporters, after five years in detention in Beijing and three years after his closed-door trial.
Yang opted not to appeal the decision, his family said, so as not to delay urgently needed medical care for a serious kidney condition. Yang remains in prison.
Details of the case have not been officially released.

Yang has said he never worked as a spy for a foreign country, and in letters to his family from jail has denied any wrongdoing.
Yang worked for China’s Ministry of State Security for a decade starting in 1989, including in Hong Kong and Washington, before quitting and moving to Australia. The Chinese government has denied ever employing Yang.
A suspended death sentence in China gives the accused a two-year reprieve from being executed, after which the sentence is automatically converted to life imprisonment.
Australia’s ties with China have steadily improved since the election of a centre-left Labor government in May 2022, resulting in Beijing scrapping a number of trade measures imposed during a nadir in relations.
On the tariffs, the ambassador said: “We do have differences on many issues and we’re going to manage the differences wisely and maturely.”
“They’re now carrying out those investigations and things are moving on right tracks with the right direction,” Xiao said.
