Radić was eventually arrested in 1925; his confiscated papers included notes by Grigory Zinoviev, in which the Green International was referred to as a tool for "the rich landowners and the bourgeoisie". Days later, Radić signed a truce with the Yugoslav establishment, and left the Krestintern. The latter was forced to attempt recruitment in other parts of Yugoslavia, and was joined by a numerically smaller Agrarian Democratic Party, while also seeking to infiltrate and influence the HSS' left-wing. From Romania, the PȚ observed and condemned the clampdown in Yugoslavia, before rejoicing at news that the HSS had reconciled with the establishment. Nevertheless, the agrarian movement was again inhibited by the Polish Coup of May 1926, upon which the Piast Party was outlawed. Forced into exile, Piast leader Wincenty Witos moved to Prague as a guest of the IAB.
