41. The GRBP Chair reported on the results achieved by GRBP during its seventieth session (for details, see the report of the session ECE/TRANS/WP.29/GRBP/68).

42. The GRBP chair mentioned that GRBP had adopted a new series of amendments to UN Regulation No. 59 (Replacement silencing systems) and a draft technical report and Amendment No. 2 to UN GTR No. 16 (Tyres). He also indicated that the recently established Informal Working Group on Wet Grip Performance for Tyres in a Worn State (IWG WGWT) would be co-chaired by France and the European Commission.

43. The GRBP Chair mentioned that, in line with the WP.29 request, GRBP solicited views of national road administrations on the draft Resolution on Road Surface Labelling and that the main conclusions of the survey were as follows:

1. The Draft Resolution in many aspects does not seem suitable for international implementation;
2. There was not much interest expressed to pursue the issue of labelling road surfaces in the framework of GRBP;
3. GRBP and WP.29 do not seem to be appropriate fora to consider this issue, as it is currently out of their scope;
4. The issue should be communicated to the European Committee for Standardization (its technical committee CEN/TC 227) and/or to the relevant International Organization for Standardization (ISO) technical committee, if available.

45. Finally, WP.29 noted that GRB had re-elected Mr. S. Ficheux (France) as Chair and Mr. A. Bocharov (Russian Federation) as Vice-Chair for the year 2020.
