Germany reminded the Sub-group members of its proposal submitted to the 9th IWVTA Informal Group meeting back in March 2012 to establish a permanent group for the IWVTA process (refer to doc.No. IWVTA-09-06). Germany continued that establishing a permanent informal group linked to WP.29 and AC1 might be a practical approach and that it had an intention to submit a document on this issue at the next Sub-group meeting.
