Entity types and names of China’s companies in Latin alphabet In China, there are two entity types of limited company:


有限责任公司 / 有限公司: 中国移动通信集团 有限公司 | China Mobile Communications Group Co Ltd
股份有限公司 / 股份公司: 中国石油天然气 股份有限公司 | PetroChina Co Ltd


Questions:


Entity Types:


I wonder why they both end in Co Ltd, although they are different in Chinese.  How about use LLC/Inc? Just like France’s SARL (= société à responsabilité limitée), can China’s companies use YG (= Yǒuxiàn Gōngsī) and GYG (= Gǔfèn Yǒuxiàn Gōngsī)?
How to reconcile company names with their Latin counterparts”. Legal experts are indeed more helpful here. In United States Federal Acquisition Circular 4.2101 (2), 海能达通信 股份有限公司 is referred as Hytera Communications Corp but 杭州海康威视数字技术 股份有限公司 is referred as Hangzhou Hikvision Digital Technology Co. Why they are different?

Besides, how does 中国石油天然气 become PetroChina? Where is “Natural Gas”? I know it is a brand name, but do they have such flexibility in writing registration name in Latin alphabet?




PS I found an Amazon seller called Shenzhen Shi Chengxinqi Keji Youxian Gongsi
There is a great deal of flexibility in the writing of registered company names.

Geely—浙江吉利控股集团有限公司
Sinopec—中国石油化工集团公司
Tencent—腾讯控股有限公司

As you can see, these famous companies do not just transliterate their Chinese names into Pinyin, but come up with a more English-sounding name instead.
Wikipedia has a page on the entity types for Chinese companies. It would be ambiguous to use abbreviations like YG and GYG, since there is no true distinction between words in Chinese. A lot of Chinese people like to abbreviate “word for word”, like YXGS and GFYXGS for the examples you have brought up.
