Which countries have the biggest and most powerful militaries? (1)

The UK has urged China to be open about its "biggest military build-up in peacetime".

Foreign secretary James Cleverly delivered a speech at Mansion House in London on Tuesday calling for China to be less secretive.

However, Cleverly stressed that isolating China would be a "betrayal" of the UK's national interest.

In a keynote address to the Lord Mayor's Easter Banquet, the foreign secretary warned: “At this moment, China is carrying out the biggest military build-up in peacetime history.

“Secrecy can only increase the risk of tragic miscalculation."

But how does China's military compare with the largest foreign forces around the world?

Which country has the most active military personnel?

According to US data group the World Population Review, China has the highest number of active-duty military personnel, with more than two million members.

It is followed by India, which has almost 1.5 million, and the US, with just under 1.4 million.

North Korea isn't too far behind the US, with almost 1.3 million troops.

The only other country with more than one million active-duty military personnel is Russia, currently bogged down in its invasion of Ukraine.

The UK was in 34th place for active military personnel, with 148,500 troops.

Watch: UK warns Russia of 'severe consequences' of nuclear use

I'm well-versed in military capabilities and global defense dynamics. The article highlights crucial aspects of various countries' military prowess, such as active military personnel, military aircraft, defense spending, and nuclear warheads. Here's a breakdown:

Active Military Personnel:

The number of active-duty military personnel varies among nations. China leads globally, boasting over 2 million members. Following China are India, the United States, and North Korea, each with significant numbers of active military personnel. Russia also stands out, currently involved in the Ukraine conflict. In contrast, the UK holds a position considerably lower, with approximately 148,500 troops.

Military Aircraft:

The quantity and distribution of military aircraft also reflect a nation's military might. The United States dominates this sphere with a significant arsenal of over 13,000 military aircraft across its air force, army, navy, and marines. Russia follows with more than 4,000 aircraft, primarily in its air force. China ranks third with over 3,200 aircraft spread across its armed forces.

Military Spending:

Military expenditure is a critical aspect, with the US leading by a considerable margin, spending close to $900 billion in 2022. China stands second, allocating nearly $300 billion, while Russia trails in third place with approximately $90 billion. The UK also invests substantially, ranking sixth globally, with a military expenditure of almost $70 billion.

Nuclear Arsenal:

Regarding nuclear capabilities, nine countries possess around 12,500 nuclear warheads, with Russia and the US holding 89% of the total inventory. Russia leads with 5,889 nuclear warheads, while the US holds 3,708. China possesses 410 warheads, and the UK has a stockpile of 105 nuclear weapons.

These figures underscore the global distribution of military power and illustrate the key players in today's geopolitical landscape. Understanding these statistics provides insight into the balance of power and potential implications for international relations and security.

The concerns raised by the UK regarding China's military buildup signify the significance of transparency in global defense strategies to mitigate the risk of misunderstandings and potential conflicts arising from secrecy.
