"The delegates are joining a meeting of the Environmental Working Group," the deputy naval chief of staff, Vice Admiral Marsetio, said on the sidelines of the opening of the symposium here on Wednesday.
The 14 participating countries include Indonesia, Australia, Brunei Darussalam, China, Malaysia, Papua New Guinea, Canada, the Philippines, Singapore, and the United States.
The symposium would focus on environment-related issues, following up on the outcome of the previous symposium held in Tahiti in 2011, Marsetio said.
He added environmental issues were important because they had "implications for the existence of life on earth".
"The environment-related issues include global warming and marine pollution. Therefore, a number of delegates will plant trees near Ecopark at the Jaya Ancol Dream Land in Jakarta. We want all countries in the Pacific region to care about the environment," he said.
