Geographical Subdivisions
The exact size of the continent is actually in dispute. The reason is that geographers cannot agree on what countries and regions to include. For the sake of convenience, the continent has been divided into regions. The following are the current regions in Asia and their approximate areas.
Note: Australia is considered a separate continent.
Central Asia
There is no agreement on what nations and regions are included here. But generally Kazakhstan is included as well as Uzbekistan, Kyrgyzstan, Tajikistan, Turkmenistan, Afghanistan, Iran and Mongolia. The size of Asia’s central territory can get confusing because parts of China are sometimes included.
East Asia
This includes the countries of Japan, Mongolia, the Korean Peninsula, Taiwan and eastern portions of China. Sometimes East Asia is geographically grouped with other Southeast Asian nations.
Northern Asia
This area refers to Siberia, Kazakhstan and Mongolia. When Northern Eurasia is used, it refers to all the former USSR regions.
Southeast Asia
The countries belonging to the mainland region are Burma, Vietnam, Thailand, Laos and Cambodia. The maritime nations of Southeast Asia area are made up of Brunei, Malaysia, the Philippines, Indonesia and Singapore. When assessing the size of Asia, this territory can get confusing; as stated, East Asia countries are often included.
Middle East or Southwest Asia
This section has numerous subdivisions. They include Anatolia (Turkey and Cyprus), the Near East (Israel, Jordan, Syria, Lebanon and Iraq). Egypt is also included in the Near East bloc even though it is part of North Africa. The Arabian Peninsula is composed of Qatar, Saudi Arabia, the United Arab Emirates, Oman, Kuwait, Yemen
and Bahrain.
The Caucasus Region
This is made up of portions of Russia, Armenia, Georgia, Azerbaijan, and parts of Afghanistan, Iran, and Pakistan.
South Asia
They include Afghanistan, India, Bangladesh, Pakistan, Sri Lanka, Nepal and the Maldives.
Note: anyone studying the size of Asia’s regions should not be surprised by the fact that countries are often included in two regions. This is to be expected owing to differing geographical interpretations.
