In a statement issued by Istana Abdulaziz, Tengku Hassanal raised concerns over a planned military training activity in Pahang’s islands, which he said could affect the environmental ecosystem, flora and fauna.

He said he does not object to military training to improve soldiers’ skills but stressed that it must be done in a “controlled and responsible manner, and in harmony with the environment and all parties”.

“His Royal Highness commands that the armed forces and all parties must comply with and uphold this royal advice,” the statement read.

“He will not hesitate to request the state government to take appropriate action should any breach of procedure occur.”

The statement did not name the islands or exercises involved. Pahang’s islands include Tioman Island and others near Rompin and Pekan.
