Here's a quarterly magazine of essay collections, the translation of which is done in collaboration with the Tricontinental Institute. Might not be all about Marxism but they are:

Quarterly Journal of Chinese Thought

Wenhua Zongheng (文化纵横) is a leading journal of contemporary political and cultural thought in China. Founded in 2008, the journal publishes issues every two months, featuring articles by a wide array of intellectuals across the country and building a platform for discussion of different ideological positions and values in China’s intellectual community. The publication is an important reference for debates and developments in Chinese thought, on matters ranging from China’s ancient history and traditional culture to its current socialist practices and innovations, from the important cultural trends in contemporary Chinese social life to Chinese views and analyses of the world today. Tricontinental: Institute for Social Research and Dongsheng have partnered with Wenhua Zongheng to publish an international edition of the journal, releasing four issues per year featuring a selection of articles that hold particular relevance for the Global South.

In Chinese, the word ‘Wenhua’ (文化) means ‘culture’ as well as ‘civilization’, while ‘Zongheng’ (纵横) literally means ‘verticals and horizontals’, but also alludes to the strategists who helped to first unify of China, roughly 2,000 years ago through diplomacy and alliances. It is impossible to translate the journal’s title into English while retaining its historical meaning and significance, therefore, we have chosen to keep the pinyin romanisation of the title to remind our readers: China has a complex history and culture that is challenging to translate and navigate, and this project seeks to bridge this understanding.

Among these essays, you might find some recent trends and thoughts among Chinese intelligentsia on socialism and western imperialism, among other things.

Roland Boer's SWCC, a guide for foreigners is good

I would actually recommend you to use (chat)GPT to translate Chinese language resources. If you want to find resources on, say, how to maintain the dictatorship of the proletariat, you can ask ChatGPT for a search query in Chinese regarding this subject. Then, you can go to Baidu.com and search for it and find a source. Then ask ChatGPT to translate it for you.

I remember hakim mentioning swcc lectures

Just out of curiosity, where can I find thoses chinese translations of hakim and yugopnik's videos?
