第4條
If information is requested by a Contracting Party in accordance with this Article, the other Contracting Party shall use its information gathering measures to obtain the requested information, even though that other Party may not need such information for its own tax purposes. The obligation contained in the preceding sentence is subject to the limitations of paragraph 3 but in no case shall such limitations be construed to permit a Contracting Party to decline to supply information solely because it has no domestic interest in such information.
