Both have blue tip.
Both are probably either for replace or supplement the license build Russian DP-61 55mm anti-frogman rocket currently in service with the PLAN. Noted that the new Chinese 35mm and 60mm are grenades fired from rifled barrel, which should have the advantage of ammo capacity, accuracy and range. The DP-61 is one rocket tube per round. The 35mm and 60mm could be magazine or belt feed. Of course the 35mm could be fired from the existing Type 87, 04 and 11 automatic grenade launchers. The 60mm looks like a scaled up 35mm grenade.
