Taiwan is considering extending conscription beyond the current four months in light of Russia's invasion of Ukraine.
This is currently being examined, Defense Minister Chiu Kuo Cheng said in parliament on Wednesday.
A plan will “definitely” be presented this year.
"We must consider the enemy situation and our defense operations in terms of military strength," Chiu told lawmakers.
Taiwan has changed from a conscript to a dominated professional army.
But growing pressure from China on the island and the Russian invasion of Ukraine have sparked a debate about strengthening civil defense and the army.
In recent years, the ruling Democratic Progressive Party and the largest opposition party, the Kuomintang, have reduced conscription from more than two years to the current four months.
They wanted to appeal to younger voters after political tensions between Taipei and Beijing eased.
Taiwan's military is a dwarf compared to that of neighboring China.
Strategists say, however, that better training could provide an advantage in a conflict.
The government is therefore also working on a program to reform reservist training.
Taiwanese President Tsai Ing Wen is also leading a comprehensive modernization program designed to make the island's armed forces more mobile and agile, using the concept of "asymmetric warfare".
The government in Beijing claims the democratically governed island for itself and wants to bring it under Chinese control, if necessary by force.
US President Joe Biden recently sent a delegation of senior defense and security experts to Taiwan.
He wanted to set a sign of support for the island.
