Jerusalem March happens annually with the Sukkot (one of three pilgrimage festivals in Judaism) and is largely organized by the International Christian Embassy Jerusalem and attended mostly by Christian evangelicals.
Edit: obviously these "delegations" are not government sponsored. Christian evangelicals just like to make a big thing out of "proclaiming to all nations" with flags and such.

It is "an exciting way to show your nation loves Israel" to quote this promotional video.
Here is a short video of the parade in 2019. (also worth noting the significance of rainbows in Judaism/Christianity relates to the seven laws of Noah)
