Dear Comrades,
At this particular and crucial period of the struggle of
the Sudanese peoples against imperialism and its local lakays
,and overthrowing of the ruling military-civilian
authority,the Sudanese Communist Party conveys its
revolutionary greetings to the 21st Congress of the Communist
Party Of Greece,wishing the Congress every success in its
deliberations to once more assert the leading role of CPG on
the struggle of the labour and people movements for socialism
in Grece.
The SCP,basing itself on the combative and fraternal
relations that are cemented through years of cooperation and
solidarity stress the recognition of the important role played
by the CPG in reviving and developing the international
communist and workers movements.
On many occasion our Party has attended several Congresses
of the CPG.WE were witnesses to the creative debates that
characterized your previous Congresses.WE are sure that the
21st Congress will add not the experience and the future of
the struggle of the Greek labour movement,but will form an
important contribution to the struggle of the international
working class movement.It will help to raise to higher levels
the banners of proletariat internationalism..
Secretariat of the CC of the SCP
