China sets its fifth plenum for October 26 with party discipline already on the agenda

Thirty to forty seats out of 205 is between 14.6 and 19.5 per cent of the Central Committee, and that is the turnover Hong Kong and Taiwan media have floated for the October session, military seats included ^[11][3][13].

When a senior figure holding a Central Committee seat is removed over corruption or another serious case, the Central Committee gives final endorsement to the action taken against that person ^[9].

The Politburo has also done the paperwork on the agenda. On the 21st it reviewed feedback gathered inside and outside the party on a draft titled the party central leadership's decision on several major issues in persistently advancing the comprehensive and strict governance of the party. It decided to submit the document to the fifth plenum after incorporating revisions ^[6]. The Politburo said the party must "properly rectify and resolve the prominent problems facing party building". It must also "consolidate and develop the sound political situation created through party governance, and open a new chapter in governing, rejuvenating and strengthening the party in the new era" ^[7]. The South China Morning Post reported that the decision was taken at Monday's meeting of the 21-member Politburo, chaired by Xi Jinping ^[2].

Then the economic question. Under the convention that took hold after 1992, seven plenums fell in each five-year term of the Central Committee. The third laid out a blueprint for five years of economic policy and the fifth took up the next five-year plan ^[4]. That pattern held through the two decades of the Jiang Zemin and Hu Jintao eras ^[5]. It stopped holding in Xi's third term, when the third session was delayed and the five-year plan was decided at the fourth ^[8]. Anyone positioning for a five-year blueprint in late October is positioning for a document that has already been through a plenary session.

A sequence rearranged once can be rearranged again, and nothing in the announcement confines the plenum to the one drafted document ^[6]. And the calendar beyond October is loose. A party congress is set for the second half of next year to launch the 21st Central Committee, so the 20th may not hold all seven sessions. That would leave the two slots after this one unused ^[10][14].

What the record supports is narrower than the precedent argument. It supports fixed dates, a 205-member body that meets once or twice a year on policy direction and senior personnel, and one governance decision queued for submission ^[1][3][6]. Seoul Economic Daily reported that observers expect the session to focus on political and ideological rectification ahead of next year's congress, which will determine whether Xi begins a fourth term ^[12]. I would treat four days in late October as a personnel event, and read the economic content off what the fourth plenum already decided ^[8].
