Thanks ROBMED for this update. Good that the consulate did something.
And again this shows: "If it looks to good to be true it probably is"

Can we get this clearified: What do you means with a Chinese Greencard?

Peters99 conclusions here and on the parallel discussion, are what scientist call hearsay. To really find out if there is malaria in an area one has to do a proper study and know what the parameters are. One has to take into account as well that in areas with malaria the local population has build up some level of resistance and they experience malaria more as a common fever. A household survey is needed because one does not see malaria patients walking in the street. As well asking adults only is not a good thing because in area with malaria the grownups don’t suffer that much and malaria is more regarded as a children’s disease.
There can be a tendency as well to downplay the issue in order to not worry you, not to scare away tourist or possible investors, not to look backward.
Only observation does not work; example: I never saw a blind person in Kunming so there are no blind people in Kunming.

@Burgon
Malerone is a brand name drug also the patent expired some years ago. Still there is no Chinese supplier. Since it has been marketed mainly as a prophylactic it was mainly aimed at the tourist/traveller section and this enabled Glaxo Wellcome to keep the price very high. These factors make it very unlikely to find the drug here in Kunming.

The area you go to has not a high prevalence of malaria and if you pick it up it can be treated well and effectively nowadays, this makes the need for prophylactic treatment less of an issue. Still it is good to take precautions because there is a change of Dengue fever as well. Thus long sleeves and trousers and closed shoes (Or like Peter99 double socks) and DEET on exposed skin when you really go into the jungle or stay in farmer huts.

The “Yunnan International Travel Healthcare Centre” that Napoleon mentioned (I presume because a entry exit clinic does not exist) is at Min Xiou Section near metro station Rixin Two blocks south of the station along the river). Doubt that they have the medication but might be able to sent you to the right place.
