The Soviet Union's Luna program also included sample returns from the Moon, most notably Luna 16 which was the first such mission to complete the sample return. As Wikipedia describes the sample return:
Finally, after 26 hours and 25 minutes on the lunar surface, at 07:43 UT on 21 September, the spacecraft's upper stage lifted off from the Moon. The lower stage of Luna 16 remained on the lunar surface and continued transmission of lunar temperature and radiation data. Three days later, on 24 September, after a direct ascent traverse with no mid-course corrections, the capsule, with its 101 grams of lunar soil, reentered Earth's atmosphere at a velocity of 11 kilometers per second. The capsule parachuted down 80 kilometers southeast of the town of Jezkazgan in Kazakhstan at 05:25 UT on 24 September 1970. Analysis of the dark basalt material indicated a close resemblance to soil recovered by the American Apollo 12 mission.
Thus the returned material included the sample, the capsule in which it was housed, and the parachute. The samples returned by this and subsequent Luna missions were much smaller than what was brought back by the Apollo missions, and the Luna craft were uncrewed, so the return inventory from these spacecraft was much less extensive than Apollo's.

Although the Luna samples are very small by Apollo standards, they do provide an independent comparison with the Apollo ones.
