For me long term objective would be
1. Solidifying infra at border throughout the LAC and making permanent infra ,treating whatever we have in control at the moment as the fixed boundary (infra wise). Specially in AP
2. All this while keeping claim on aksai C while doing no talks of AP region and giving once in a while statement like they claim ours AP.
3. Salami slicing strategically and constant intrusions like they do to us.
In all i think that what is govt or army is doing right now but iam 100% sure this will once again vanish if chinks start to comply. So last point comes.
4. Forming a forward policy or a seperate division that deals it like a 5 year plan ( military wise) to at least have some goals in future regarding china now that we know their intension is not friendly. And even if chinaman temporarily obliges keeping that offensive goal alive in background to secretly eliminate the differences in military development etc while keeping a welcoming face for Chinese
