SINGAPORE - The Commander-in-Chief of the Royal Thai Air Force, Air Chief Marshal Treetod Sonjance, called on Singapore's Defence Minister Ng Eng Hen on Wednesday morning.

The Thai air chief also called on his Singaporean counterpart, Major-General Hoo Cher Mou.

As part of his three-day introductory visit, the Thai air chief will, on Thursday, co-officiate at the opening ceremony of Exercise Cope Tiger - an annual military exercise involving the air forces of Singapore, Thailand and the United States.

He will also visit the Republic of Singapore Air Force's 111 Squadron, which operates the Gulfstream G550 airborne early warning aircraft, said Singapore's Defence Ministry.

His visit underscores the close and long-standing defence ties between Singapore and Thailand, it said.

It added: "Both air forces interact regularly through exercises, professional exchanges and courses. These interactions have bolstered the friendship and mutual understanding between the personnel of the two air forces."
