The New York trial of a prominent Hong Kong businessman charged in a United Nations-linked bribery conspiracy is set to begin with jury selection Monday.

The trial of Dr. Chi Ping Patrick Ho begins a year after he was arrested on charges accusing him of paying bribes so a Chinese energy conglomerate could secure business advantages. He has been held without bail.

His lawyer has said Ho is looking forward to clearing his name. Ho was once Hong Kong's home affairs secretary.

Ho has insisted he is not guilty of charges that he conspired in October 2014 to bribe the president of Chad and the Ugandan foreign minister.

Prosecutors say Ho's former co-defendant, Cheikh Gadio, will testify at trial that Ho arranged a $2 million bribe to be delivered to Chad's president in gift boxes.

Last Wednesday, U.S. District Judge Loretta A. Preska overruled defense objections, saying Gadio can testify that he understood Ho's $2 million cash payment to President Idriss Deby to be a "bribe."

Ho's lawyers had argued that Gadio's testimony as to whether the $2 million was a "bribe" was lay opinion and should be kept out of evidence the jury can consider.
