We point out the strong correlation between the [ital CP]-violating asymmetries in the decays [ital B][sup 0][r arrow][Psi][ital K][sub [ital s]] and [ital B][sup 0][r arrow][pi][sup +][pi][sup [minus]] that is predicted by the Kobayashi-Maskawa model. This results in a very restricted allowed region for the asymmetries, and so their measurement will provide a powerful test of the standard model. To show how new physics may give very different results, we look at the predictions of a simple model where both the standard model and superweak contributions to the [ital K][sup 0] and [ital B][sup 0] mass matrices coexist. We find that, for possible values of the parameters, practically any values are allowed for the asymmetries.
