Brasília, 28 (Agência Brasil - ABr) - According to the Monetary Policy Committee (Copom), the international situation has improved, but still calls for caution. The minutes of the last Copom meeting express belief in the possibility of economic recovery in the United States before the end of the first half of the year. However, Copom members warned that the crisis in Argentina and events in other Latin American countries also require close attention. According to Copom, positive signs are the relatively stable situation of both the exchange rate and Brazil risk ratings. (AB)
