The vessels were the Great Wall 218 conventional-powered submarine, Type 054 frigate FFG-526 Wenzhou and the Peace Ark hospital ship.

The ships, all independently designed and made by China, represented the latest stage of PLA Navy equipment, Gu Wengen, deputy commander of the force, told Xinhua Wednesday.

According to Gu, the invitation to the foreign delegates was intended as the latest move by the PLA to demonstrate its military transparency.

Commissioned in September 2005, the Wenzhou is one of the most modern frigates in the service of the PLA. At 4,000 tonnes, the frigate is even larger than many of the PLA's destroyers, according to Gu.

The Great Wall 218 conventional-powered submarine is also one of China's new-generation submarines equipped with world-class sonar and weapon systems, he said.

The Peace Ark hospital ship can provide seagoing medical services equal to those of a top hospital in Beijing.

All three vessels were commissioned in just the past few years, said Gu, adding that the Peace Ark only went into service in December.

"Foreign naval officers can not only learn about the modernization of China's navy by visiting the three vessels but can also feel our sincerity to expand cooperation and exchange with our foreign counterparts," Gu said.

After a quick tour of the Peace Ark, Capt. James Fanell with the U.S. Seventh Fleet, who came from the naval base in Yokosuka, Japan, said that he was glad to see the increasing openness of the Chinese navy.

"I was here five years ago on the USS Cushing. The openness shown by the international fleet review is much greater than that of five years ago," Fanell said.

"It is very encouraging and appreciated to be able to walk aboard the ship and see ships of the Chinese fleet as well as other ships of the international community," he said.

For Adm. Moura Neto of the Brazilian Navy, the Chinese navy's transparency was as surprising as its modernization.

"I saw the real China and the real PLA navy," he said.
