The resort community of Beidaihe has seen tightening security in recent days - one of several signs that Communist Party chiefs would soon be arriving for their annual policy conclave there.
Increased numbers of armed police have been seen in the vicinity of a private Beidaihe beach. Also, 200 "model workers" - people the party has recognised for their contributions to society - have recently arrived for holiday in the area, the China News Service reported.
Last year, President Xi Jinping held a meeting with grass-roots workers in the resort ahead of the "summer summit", when the party attempts to thrash out issues in advance of its formal fall meetings.
State-broadcaster CCTV reported yesterday that Xi visited troops in Beijing command ahead of holiday Army Day on Thursday, calling on the soldiers to be loyal to the party.
The party chiefs may discuss the case of disgraced Chongqing party chief Bo Xilai , but analysts said the saga would not be a focus since his corruption indictment has been filed.
