Generally 稅局個interpretation 係咁 睇番secondary filing 個rules 其一個condition precedent: upe outside hk which entered into international agt with hk but auto exchange is not in effect,稅局對international agt 個解釋係一個agt which allows auto exchange 而tiea 係唔allow auto exchange (i.e eoi upon request) 所以tiea 唔算一個international agt,換言之 呢個condition 唔成立, and 香港冇secondary filing
