Alibaba and Coupang are two big companies that help people buy things online in different countries. They both want to be the best, so they are trying to grow bigger and stronger by spending a lot of money. South Korea is an important place where they can make more sales, so they are putting more money into it. But there are other companies like AliExpress that also want to sell things online in South Korea, so Alibaba and Coupang have to be careful and try to do better than them. They are also trying to sell different kinds of products like food and groceries, because those are hard for their rivals to do well. Read from source...

1. The title is misleading and sensationalist, as it implies a direct competition between Alibaba and Coupang, while the article focuses on their investments in South Korea, not their e-commerce platforms or services.
2. The article does not provide any data or evidence to support the claim that Alibaba and Coupang are intensifying their e-commerce battle, nor how their investments affect the market share or customer demand in South Korea.
3. The article uses vague terms such as "major investments" and "intensify", which do not convey any specific information about the scale, scope, or timing of the investments. These terms also create a negative tone and bias towards Alibaba and Coupang, implying that they are aggressively expanding their presence in South Korea at the expense of local players or other foreign competitors.
4. The article relies on secondary sources such as Benzinga and Nikkei Asia, which may have their own motives or biases to report on Alibaba and Coupang's activities in South Korea. These sources also do not provide any primary data or insights from the companies themselves or independent experts.
5. The article mentions several irrelevant details such as AliExpress's strategy, Naver's market share, and Coupang's diversification plans, which do not directly relate to Alibaba and Coupang's investments in South Korea or their e-commerce battle. These details also introduce more confusion and noise rather than clarity and relevance.
6. The article ends with a price action update that does not reflect the main topic of the article, nor provide any context or analysis of how the market reacted to Alibaba and Coupang's investments in South Korea. This update also seems out of place and inconsistent with the tone and focus of the rest of the article.
