RHU's and RTG's, at least

why? RTG technology is well known in China. After all, Chang'E 3 uses a Chinese RTG

Can you point to an authoritative source confirming that?. According to Rosatom press releases, it was made at VNIIEF, or at least was significantly helped

I'm not sure what Russia brings to the table to benefit China at this point, but this collaboration might be more for political than technical reasons.
Not really. We already knew YF-100s were derived from RD-120s. R&D independently is always hard, CASC has a strong desire to acquire Russia's powerful engine(RD-180s) and heavy rocket technology these years

RD-180 may be the only jewel that China is interested in. But as far as the rest, Chinese rockets already out-lift the Russian ones, and the future CZ-9 is not dependent on RD-180 technology.

Is a Rosatom press release an authoritative source?  Sometimes credit is claimed for a fairly small involvement.  I'm not saying they were not involved, even in a big way, but an outside source would be better.

Well the two articles linked above claim an official contract between GWIC and Glavkosmos, and specifically call out the types of devices being built too. There would likely be other public records in Russian detailing the contract sizes etc.

I'll be lazy and post the google translated versions here. From my admittedly rusty reading of Russian versions, its decently accurate

From June 12 to June 15, a working meeting of the delegations of RFNC-VNIIEF and OAO Glavkosmos with Chinese specialists from the Tianjin Institute of Current Sources, the Industrial Corporation "Great Wall", the Center for Moon Research and Space Engineering of the CNPC was held in the Sarov Technopark. This was reported by the press service of the Institute.

The meeting took place within the framework of the Russian-Chinese contract on the moon sounding program. The Chinese side presented the results of the work of the nuclear center for the creation of radioisotope sources of heat and electrical energy.

So, the newest joint development was carried out by EMV Avangard and KB-1 VNIIEF. This is a radionuclide thermal unit with a power of 120 watts. And a radioisotope thermoelectric generator with an output power of 6.5 watts. The KB-1 specially designed a transport packaging for transportation of radionuclide thermal blocks.

At the meeting, specialists of the VNIIEF emergency technical center demonstrated to the Chinese representatives the method of handling the transport packaging. The uniqueness of the kit is the ability to transport nuclear materials not only by road or rail, but also by air.

"The high level of development of VNIIEF is confirmed by a certificate for the safe use of a thermal unit in outer space issued by the Center for the Certification of Rocket and Space Equipment," the source said. A certificate of approval for the construction and transportation of a transport packaging with a thermal unit has been issued by the competent body of Rosatom State Corporation.

The VNIIEF successfully completed the development, production and supply of 120W radionuclide thermal blocks of space in the PRC. This was reported by the press service of the Institute.

The visit of the delegation of the nuclear center to China was the final stage of fulfilling the contracts between JSC "Glavkosmos" and the Chinese industrial corporation "Great Wall". Chinese experts highly appreciated the quality of the delivered products.

Specialists KB-1, KB-2 and EMZ "Avangard" participated in the implementation of the contracts.

Earlier, the nuclear center supplied the Tianjin Institute of Current Sources with radionuclide blocks with a power of 4 and 8 W and an engineering model of a radionuclide thermoelectric generator.

In 2012, Sarov scientists presentedChinese specialists radionuclide thermal unit - at that time the newest joint development of EMV Avangard and KB-1 VNIIEF. The meeting was attended by representatives of the Center for the Study of the Moon and Space Engineering of the CNDK.

Also,  last year VNIIEF demonstrated isotope blocks at the XII International Exhibition of Nuclear Industry "NIC 2012" in China.
