New data are presented on J/ψ→ωK+K− from a sample of 58M J/ψ events in the upgraded BES II detector at the BEPC. There is a conspicuous signal for f0(1710)→K+K− and a peak at higher mass which may be fitted with f2(2150)→KK¯. From a combined analysis with ωπ+π− data, the branching ratio BR(f0(1710)→ππ)/BR(f0(1710)→KK¯) is <0.11 at the 95% confidence level.
