Dear Prashantji,

I'll go with Persicaria chinensis once again. Colour variation is
common in this sps. and so many varieties have also been reported
based on the shape of the leaf. Your photographs shows insect fed
leaves of the same along with the leaves of Mikania micrantha.
Therefore, I would request you to post some pictures focussing more on
leaves to identify the plant with certainty.

Regards,
Ritesh.

Ritesh ji

Yes because of accrescent fleshy perianth, but a few leaves with sagittate base are creating doubts. Yes photographs with well depicted lower and upper leaves would be crucial.

Rightfully said by Ritesh Ji In Flora of China there are reports of variation in colour and so do in many articles available on net where it says it may have white, pink and red flowers. The mix up of vegetation is creating difficulties to observe the leaf morphology!!
