The BBC has come under fire recently for paying male employees more and has pledged to close the gender gap by 2020.
In July, it revealed as part of a funding settlement with the government that it paid its then top male star five times more than its best-paid female presenter, and that two-thirds of on-air employees earning at least 150,000 pounds ($203,500) were men.
The BBC had four international editors, two men and two women, of which she was one, she said.
When the BBC revealed top salaries as part of last year's settlement, Ms. Gracie said she learned that the two men made at least 50 percent more money than the women in those roles.
She said she had since had been offered a pay increase that remained 'far short of equality' and left her post in Beijing last week, returning to her former job in the BBC TV newsroom.
'The BBC must admit the problem, apologise and set in place an equal, fair and transparent pay structure,' she said, calling for an independent arbitration to settle individual cases at the broadcaster.
The BBC cited a BBC spokeswoman as saying that 'fairness in pay' at the corporation is 'vital', and that an audit of pay for rank and file staff led by an independent judge found there was 'no systemic discrimination against women'.
Many expressed their support using the hashtag #IStandWithCarrie.
