🆕 NEW ENTRY — 291 China Resources Beer (Holdings) Co. Ltd. ← The Bank of New York Mellon Corporation, 5.09% (increased by 0.15pp from prior filing; aggregate crossed 5% as a related custodial entity's filing lapsed) Read: BNY Mellon's custodial book in China Resources Beer grew past 5% even as one related entity's filing formally "ceased" — the aggregate is rising, not exiting.

🆕 NEW ENTRY — 9927 Seres Group Co., Ltd. - H Shares ← BlackRock, Inc., 5.48% (increased by 0.96pp from prior filing; aggregate crossed 5% as a related BlackRock entity's filing lapsed) Read: BlackRock's aggregate long position in Seres Group climbed back above 5% despite the "ceased" label — treat as a fresh crossing, not a sale.

🏢 BUYBACK — 3323 China National Building Material Co. Ltd. - H Shares ← BlackRock, Inc., 4.97% (decreased by 0.70pp from prior filing, issuer buyback effect) Read: CNBM's own buyback mechanically trimmed BlackRock's disclosed stake below 5% — a passive filing, not a BlackRock sale.

🏢 BUYBACK — 1138 COSCO SHIPPING Energy Transportation Co., Ltd. - H Shares ← BlackRock, Inc., 6.50% (decreased by 0.74pp from prior filing, issuer buyback effect) Read: COSCO Shipping Energy's buyback shrank the float enough to move BlackRock's percentage, not its actual holdings.

Co. - H Shares ← BlackRock, Inc., 6.83% (decreased by 1.04pp from prior filing, issuer buyback effect) Read: Yangtze Optical's ongoing buyback pushed BlackRock's stake down over 1pp, a float-shrink effect worth noting alongside the buyback's pace.
