Someone still gets counted in the case numbers even if they are treated and recover.
I believe HCQ/CQ is also being used in Spain, France, and Italy, but there are still many deaths and a high CFR. It’s not a magic drug (there may or may not be some good effects from using it, and studies are ongoing), but some political leaders are touting it in desperation, while medical leaders are pointing out that scientific trials are ongoing to determine if it’s really working or not.
First, tell us why you claim India has this 'under control'?
According to John Hopkins stats[1] (as of 2020-04-06:2200+11) shows India (population 1,600m) with confirmed case count of 4,300.
Meanwhile Australia, who's been relatively slow to trace and test, population 25m, with confirmed case count of 5,800
It's possible these numbers reflect realities, but it's a hard sell.
> ... and are using Chloroquine almost exclusively for the treatment?
This is going to need some even better citations, especially if the implied claim is that they're almost exclusively using Chloroquine for treatment with great success.

I don't believe either of those points is valid or compelling.
'Death rate' ... is a highly ambiguous term.
Case Fatality Rate (or equivalent) is the measure of mortality (attributed to the disease) per identified case. Obviously this metric can be easily hacked -- test fewer people so you have fewer confirmed cases.
Infection Fatality Rate (or equivalent) is the measure of people we estimate had COVID-19 and died from it, even if they weren't confirmed via testing. In countries that have been very slow to test, this number is expected to be relatively high, though not as frequently reported on.
It's very unlikely that IFR would vary significantly, absent significant medical intervention, between races / cultures / locations / etc.
EDIT: Citing The Atlantic last month: "For one, India is still not testing enough people, having conducted the fewest number of tests of any country with confirmed cases of the coronavirus, at just 10.5 per million residents (South Korea, by contrast, has conducted more than 6,000 tests per million residents). "
As to the Indian government's confidence being high ... there's no shortage of political hubris going around, and Modi's not immune.
I note that at the end of March "a $22.6bn economic stimulus plan [...] to provide direct cash transfers and food handouts to India's poor."
This does not sound like something that anyone in India believes is 'under control'.

My guess is doctors in India have experience with chloroquine because it is useful for malaria, something that Swedish doctors would not be expected to have experience with. If Swedish doctors spent 6 months reviewing all the knowledge India has they might be able limit side effects and see good results.
Remember, the first paragraph is the truth, but not helpful. The second is an educated guess, it seems likely but it may well be wrong.
