The corpus holds no public PRC document announcing strategic-petroleum-reserve moves — those are not disclosed. What the record actually shows on your two questions:
· Reserves: analysis (largely 观察者网/Guancha) arguing China's large reserves + diversified supply cushioned the Iran War; the only reserve-drawdown policy item here is the US SPR, not China's.
· Imports: the evidence points the opposite way from a pause — Chinese independent refiners bought more discounted Mideast/Iranian crude, and the one concrete PRC action, the MOFCOM blocking order (2 May), protected those purchases against US sanctions. Government voices are limited to MFA/MOFCOM statements and Hormuz responses.
