Nanjing Automobile has committed itself to Longbridge for at least ten years, it has emerged.
The Chinese car maker will remain in Birmingham for at least the next decade after it failed to invoke a six month get out clause with landlords St Modwen.
St Modwen revealed the next break in the 33-year lease, which was signed in February, would not expire until 2016.
Bill Oliver, chief executive of St Modwen, said: "This was not a done deal and there has been a lot of uncertainty, but Nanjing have committed to it and I take that very positively.
"They are there and they are paying rent and we are very pleased. This commits them to at least ten years."
The company aims to restart production of the MG TF sports car in Birmingham.
