Michael Kovrig, a Canadian former diplomat, has spoken about his experience being detained by China for over 1,000 days.
He describes being held in solitary confinement for months and subjected to daily interrogations lasting up to nine hours, which he believes constituted psychological torture.
During his imprisonment, Kovrig missed the birth of his daughter and only met her for the first time when she was two-and-a-half years old.
Kovrig's account highlights the harsh and potentially harmful treatment he endured while in Chinese custody.
