Thank you for your reply. Now it is clear to me that I must not declare losses on foreign retirement plan.
it is a bit unfair that the IRS does not treat foreign retirement plans same as domestics, especially when we are forced to have and cannot get any distribution until retirement age. so basically we are getting punished getting taxed with gains every year and forfeit any losses when they occur. Paying Taxes on undistributed gains is for sure a punishment to people who had no choice to withdraw the funds even before becoming US residents.
Regards,
