Wasn't the 1980s but even further back in the 1920s. This TV show in the screenshot is actually an essay written in 1925 by a Chinese socialist thinker and this meme of China claiming Marx was Chinese is an out of context mistranslation.

A commenter on a post where this was posted earlier pointed out that Diderot and other enlightenment thinkers admired Qing China's civil service, and that these thinkers (being part of a "radical" rather than mostly angloamerican "liberal" intellectual tradition), would influence Kant, Hegel, Marx and Engels.

In 1925 the Communist writer Guo Moruo published a short story entitled ‘Marx Enters a Confucian Temple’. It tells of a conversation between Marx and Confucius, in which Marx is asked to explain his idea of a Communist society, Marx does so, after which Confucius is unable to contain himself, clapping his hands and crying out: ‘Your ideal society and my world of datong coincide with each other’. Thereupon, Confucius quotes the text from Liji:

"When the Great Way [dadao] was practiced, all-under-heaven was as common [tianxia wei gong]. They chose men of worth and ability [for public office]; they practiced good faith and cultivated good will [xiumu]. Therefore, people did not single out only their parents to love, nor did they single out only their children for care. They saw to it that the aged were provided for until the end, that the able-bodied had employment, and that the young were brought up well. Compassion was shown to widows, orphans, the childless, and those disabled by disease, so that all had sufficient support. Men had their portion [of land], and women, their homes after marriage. Wealth they hated to leave unused, yet they did not necessarily store it away for their own use. Strength they hated not to exert, yet they did not necessarily exert it only for their own benefit. Thus selfish scheming was thwarted before it could develop. Bandits and thieves, rebels and traitors did not show themselves. So the outer gates [waihu] were left open. This was known as the period of the Great Unity [datong]"

In reply, Marx calls Confucius an old comrade (lao tongzhi) and observes, ‘Your opinion is completely consistent with mine.’
