The fundamental reason for this phenomenon lies in the existence of two vastly different cultural systems.
In Chinese culture, the principle of "honoring one's word" (delivering on promises) is of central importance. If entities such as AVIC, SAC, CATIC, or other official bodies were to comment on or express opinions regarding potential export orders for the FC-31/J-35 at the initial stage of interest, public expectations would immediately soar.
In reality, however, numerous factors influence such prospective orders, and their actual conclusion is far from certain.
Should a deal fail to materialize, these organizations would face public scrutiny and skepticism. The consequences of making bold claims that do not come to fruition are severe; the public would seriously question the organization's credibility and might even re-evaluate its past reputation, potentially plunging the entity into a profound crisis of trust.
In Pakistan, such actions might elicit verbal criticism or public backlash, but in China, the repercussions can be far more drastic: individuals could be dismissed and their careers permanently ended. In particularly serious cases, those involved might even face legal liability.
Consequently, these organizations generally refrain from making statements until a deal is fully confirmed.
