During the 12 years Lauchlan Campbell spent inside Shanghai's Ti Lan Qiao and Qing Pu prisons, his younger brother was behind bars 10,000km away in one of Britain's toughest jails - Scotland's notorious Barlinnie Prison.
But while Lauchlan, now 54, was guilty of his crime - smuggling 7.5kg of cannabis - Thomas 'TC' Campbell was wrongly convicted, along with his co-accused Joseph Steele, of killing a family of six in an arson attack as part of gangland feud in 1984.
The men spent 20 years battling to clear their names in what has been described as the biggest miscarriage of justice in Scottish legal history.
Their crusade ended in March this year when their convictions were quashed after the man whose evidence sent them down admitted he had lied during their trial.
Uncannily, Thomas' vindication came just weeks after his brother's release from jail in Shanghai in February this year.
It has left the elder brother angrily contrasting his treatment as a guilty man in China with his innocent brother's 20-year fight against injustice in Scotland.
Lauchlan, who is back in Glasgow and has been working as an interior decorator, recently told the Scotland on Sunday newspaper: 'When I was in prison in China I used to write to my brother and tell him to take a deal - get out. But he didn't listen and it's just as well he didn't because he's innocent.
