The Canadian embassy in Beijing said Tuesday that a Chinese-Canadian businessman has been put on trial in China without consular access five years after going missing from an opulent Hong Kong hotel.

"Canada made several requests to attend the trial proceedings of (the) Canadian citizen, Xiao Jianhua. Our attendance was denied by Chinese authorities," the embassy said in a brief statement.

The statement said embassy officials were "monitoring this case closely", and would "continue to press for consular access".
