We report on the detection of 12CO emission in the rotational transitions J=1-0 and 2-1 towards four selected regions along the eastern flank of the Puppis A SNR, where previous low resolution observations revealed the presence of an extended molecular cloud. The observations were carried out on March 2000 using the SEST telescope located in La Silla (Chile). The angular resolutions are 45" and 23" for both transitions respectively. From the analysis of these observations, it can be concluded that there are possibly associated molecular features at two different velocity ranges: v_lsr~+3 km/s and v_lsr~+16 km/s. The effects of the mutual interaction SNR/shocks are analyzed.
