Clive Carter, 34, of Motherwell, is accused of murdering 42-year-old Khanokporn Satjawat at the SECC on Monday. He allegedly attacked the woman with a weapon in a second-floor female toilet at the Clyde Auditorium.
Ms Satjawat, a manager at global pharmaceutical giant Bristol-Myers Squibb (BMS), was attending as a delegate at an HIV treatment conference when she was found at 2.30pm. She was pronounced dead at the scene by paramedics.
Carter appeared before Sheriff Danny Scullion and is expected in court again next week.
BMS is celebrating its 125th anniversary this year. A spokesman for the firm said: "I can confirm one of our employees, Khanokporn Satjawat, died unexpectedly while travelling on company business. We are shocked and saddened by the events surrounding our colleague's death."
A spokesperson from the SECC said: "We have been informed that a man has been charged in relation to the death of a female visitor at our premises on Monday 12th November. We are continuing to work closely with Strathclyde Police and assisting them in their ongoing investigation. At this time our thoughts and condolences are with the family, friends and colleagues of Khanokporn Satjawat"
