Mr Surapong said the BTSC had written to the Bangkok Metropolitan Administration (BMA) and its investment arm, Krungthep Thanakom Co, at the beginning of the year to seek a debt settlement. In total, BTSC is seeking to recover 9.6 billion baht for operating the Green Line extension for more than three years and 20.7 billion baht for the purchase of train operating systems along the extended route.
