On the contrary, China already had existing guidelines for genetic studies, however He Jiankui went far and beyond what current science, ethics and regulations allowed.
Once the ethical and regulatory concerns for genetic editing are sufficiently mature, people like He Jiankui won't be needed because he didn't offer anything useful that other scientists in this domain can offer. All he did was act brashly, deliberately flaunting ethical considerations and ignorant of the potential harm he was doing not only to the embryos he edited but to the population as a whole by introducing these people into the gene pool.
He does not possess the integrity and reasoning to be a biophysicist let alone someone that should have access to treating participants or patients (he isn't a medical doctor, for one).
He Jiankui should be considered a disgrace. If the one thing that he should be commended for, it is for making the Chinese authorities to better recognize the threat that rogue scientists pose to participants, patients, and the general population.
There is a pathway to pursuing the role of genetic editing for human applications. Directly editing human embryos and letting them reach term, be birthed, and enter the human population all while avoiding ethical oversight, is far beyond the pale of what is acceptable.
It's not a surprise that the guy is doubling down, and if you look at his twitter account he is unrepentant, vain, and trying to exploit his notoriety for media coverage and funding.
While He Jiankui was acting against guidelines and he knew it, the actual act of him editing the babies is not wrong. People are squeamish about genetic editing for no reason. The main concern; unintended edits and unknown side effects of the edits that were made, are nothing compared to actual biological reproduction. Biology is messy, at that kind of scale , you're gonna to get replication errors everyone you have cell division. That's what causes mutations and cancer. It's just entropy and at that scale, it's unavoidable. Every time you have a child, there's dozens of unintended random very minor genetic changes, just as a result of replication errors. It's just that most of the time, this minor changes don't do much. But something you can just get some random major mutation that could cause some major never seen before disease, or be beneficial. That's literally how evolution works and how genetic disorders get created and passed on in the first place. Even for asexual reproduction, where the offspring are genetic clones of the mother, will have some minor genetic changes. Shall we ban all human reproduction because of this? After all, every time you have a child, you are just rolling the dice and praying that their particular mutations aren't harmful, it's no real difference from the the main potential side effects of gene editing.
On a more practical level, if you have to talk about "polluting the gene pool", society doesn't round up and ban people with serious genetic disorders from having as many children as they want, despite some diseases being extremely debilitating and having a very very high likelihood of passing it onto their children. Something like Huntington's disease as an example, if you have a parent that has this disorder, you have a 50% chance of getting it. If something as minor as the side effects of CRISPR editing is bad and subject to strict guidelines, why are this people allowed to have as many children as they want, despite the very high chance of them harming their children’s life by passing down this genetic diseases? And then there's minor genetic variations that select for higher risk for diabetes, asthma, stroke, heart disease, early onset dementia etc etc., no problem with them reproducing as them as they want, even though some of them can get really bad, like a long family history of family members constantly getting early cancer or early onset dementia or serious asthma.
Oh and human reproduction is a mess. Random mutation always happens. But a lot of common genetic disorders like down syndrome come about because of issues with the gametes. Like I have said, mutation and genetic drift occurs constantly, and we just constantly get more and more mutations as we age, even to our gametes. Our reproduction system has lots of safeguards in play to ensure that defective sperm doesn't meet up with a defective egg and if they do, they get purged. But it does happen and when it often does, it leads to lots of issues. That's why the older the father and mother, the bigger the chance of having genetic disorders. Shall we ban reproduction for parents over the age of 30?
Oh and there's epigenetic factors to worry about too. This field is still new, so it's very unclear as to the actual specifics, but it's clear that the environmental conditions of the mother during pregnancy can greatly influence the genetics of the child, usually in bad ways in our modern lifestyle that is awash in various drugs, bad air quality and lots of plastic. Even if you discount genetic changes, there's still disorders like fetal alcohol spectrum disorder. Have any countries made it illegal to drink/smoke while pregnant? How about making it illegal to be pregnant in cities with bad air quality? How about making it illegal to get sick while pregnant?
All this "Oh no, we're playing God, this is the end of human society" is just bullshit soapboxing. This is like people who think that GM crops and livestock is the act of the devil, but human breeding wolves into pugs and french bulldogs is fine and okay because it's "natural". We wouldn't have the dozens of genetic disorders that plague the human race if natural biology and human reproduction was anywhere as good as we think/hope it is. Most countries don’t even make it illegal for pregnant mothers to drink alcohol or smoke but somehow the potential harm of genetic engineering on children is so bad that we have to immediately make it illegal the moment that it happens.
He Jiankui should be considered a disgrace. If the one thing that he should be commended for, it is for making the Chinese authorities to better recognize the threat that rogue scientists pose to participants, patients, and the general population.
And instead of updating the guidelines or just keeping a closer watch on the process. They responded with a blanket ban on human germline editing. They should have just officially allowed the practise, but kept it under strict supervision and regulation and only for couples who have serious genetic diseases but want children anyway. As a rule, bans and regulations are much harder to remove then to put into place, doubly so for China. This also discourages researchers from even going into the field, let alone doing serious research into it.
As usual, it's gonna to be left behind in the race that causes China to wake up. Same story as always, America starts mass editing humans by the tens of thousands in 2050 and China goes "HOLY SHIT NATIONAL EMERGENCY ALERT, WE ARE DECADES BEHIND THIS THIS CRITICAL TECHOLOGNY, QUICKLY THROW REGULATIONS INTO A BIN AND POUR IN BILLIONS TO QUICKLY CATCH UP", instead of being the forerunner in this new field and setting the standards themselves.
And trust me, Chinese authorities are already very very aware and stupid when it comes to genetic technology. Just look at the state of China's GM crops industry. Only really in the last 4 years has China allowed for a trial roll out of commercial planting of GM food crops and this trial roll up is so slow that even today, major crops like GM rice is still not approved and the total land area for GM crop planting is 1% compared to conventional plant breeds. This is when China is super concerned over food security btw. GM crops have been in used in dozens of countries for decades and eaten daily by more than a billion people, but China is still so cautious because? China already imports and eats sooooo much GM food from other countries anyway, but at this rate, it will be another decade before GM crops exceed conventional plant breeds coverage on Chinese farms.
Meanwhile, countries like America have been mass planting GM crops for human consumption since the 90s and have already approved GM livestock for rearing and human consumption. If China is so cautious about a commonplace genetic technology that has been in use for decades, I wonder how they will handle human gene editing, or any of the radical synthetic biology and genetic technology coming the the next couple of decades like artificial wombs, lab grown meat, artificial blood/organs, longevity treatments, invasive brain computer interfaces, xenotransplantation etc etc. Probably blanket bans or smothering it in so many regulations that it never takes off in China.
