Indonesian Defense Minister Purnomo Yusgiantoro stressed on Friday the need to provide legal basis to secure the sustainability of the country's defense development to comply with strategic plans to reach independent phase by the period of 2025-2029.

"We at the ministry were anxious whether what we have been doing now can be continued by the successor of the present government. They probably have different vision and mission regarding this issue," the minister said in a session discussing the sustainability of the country's defense capability.

Indonesia is scheduled to hold legislative and presidential elections next year that would end the presidency of President Susilo Bambang Yudhoyono who has served two maximum five-year presidency periods from 2004.

In the discussion Purnomo pointed out that military power is the essential component of the country's sustainable defense system, backed up by military-oriented extensive researches and development.

In a bid to materialize the mightiness of national defense system, legal basis would be highly required to endorse activities aimed at addressing the aim. "The form can be government regulation, presidential instruction or even better a law," Purnomo said.

The minister added that political support from the parliament was also highly required to attain the aim as the legislative body has the authority to approve budget proposed by government to finance defense projects.

A legislator who was at presence Mahfudz Siddiq, who chairs the Commission I for defense and foreign political affairs in the parliament, said that sustainability in the development of defense sector should be addressed properly as much as in economy and legal sectors.
