Introduction:
Out of the given options, China is the country that does not have huge reserves of petroleum and natural gas. This can be attributed to several factors including geological conditions, limited exploration, and a greater reliance on other energy sources.

Reasons:
There are several reasons why China does not have huge reserves of petroleum and natural gas:

1. Geological Conditions: China's geology is not favorable for the accumulation of significant petroleum and natural gas reserves. Many of the country's sedimentary basins lack the necessary geological structures and conditions conducive to the formation and preservation of large hydrocarbon deposits.

2. Limited Exploration: China has not conducted extensive exploration and drilling activities compared to other oil-rich countries. The country started exploring for oil relatively late and has not been able to make significant discoveries of large oil and gas fields.

3. Heavy Reliance on Coal: China has traditionally relied heavily on coal as its primary source of energy. This has resulted in less emphasis on the exploration and development of petroleum and natural gas resources. However, in recent years, China has been shifting towards cleaner energy sources and increasing its focus on renewable energy.

4. Environmental Concerns: China's rapid industrialization and economic growth have led to significant environmental challenges. The extraction and production of petroleum and natural gas can have detrimental effects on the environment. China's government has been increasingly concerned about environmental issues and has been promoting cleaner energy alternatives.

5. Imports: Due to the limited domestic production, China heavily relies on imports to meet its growing energy demand. The country has been investing in overseas oil and gas assets to secure energy supplies and reduce its dependence on imports.

Conclusion:
In conclusion, China does not have huge reserves of petroleum and natural gas due to unfavorable geological conditions, limited exploration, a greater reliance on coal, environmental concerns, and a significant dependence on imports. However, it is important to note that China has been making efforts to diversify its energy sources and reduce its reliance on fossil fuels through the promotion of renewable energy and investments in overseas oil and gas assets.
