There's a lot of misinformation here. There are multiple policies in place and it relies entirely on the city as to what happens. There are 2 parts to the pension fund. The Company and the Personal contributions. ALL gains and interest are allocated to the company portion. The personal contribution is only what you personally put in and nothing else. Once you hit retirement, they draw first from the personal contribution. For most, this is pretty much nothing. Once exhausted, they move to the company portion for drawdown. Survivor benefits are based solely on the PERSONAL contribution balance. In otherwords, the large balance you see in the account is a lie. That money will never all come out. Here's where the problems lie. If you are already retired and drawing on it, and then give up citizenship.. no problem, you can keep taking it. But for many, if you have a foreign citizenship or even a green card already... they will cash you out on the personal and that's it. Nothing more. Furthermore, the "15 years" for vesting can be modified at any time. There is no grandfathering of laws in China. It's all just policy from on high. If it's a meager sum, then sure, roll the dice on it I guess, nothing to lose. But for those with good years of work left, cash it out asap and dump it into an IRA/401k or other retirement account. Medical care in China is horrid and pointless. The pensions are also rather meager. The pensions are also rife with fraud, already at a negative balance in most areas, vastly underfunded... it's only a matter of time before they "reform" the system and that assumes that the asshats in beijing will remain in power. Once they go, it's all gone anyways.
