Manila residents are complaining of difficulties getting to work and a fake image of the Philippines being presented to the world during the APEC meetings.

Roads have been closed to regular traffic in central Manila and other efforts made to spruce up the usually traffic clogged city.

Trixie Logan, 19, says it's "a bit off because it's like fake beauty, because they hid the problems around just to say that the Philippines is beautiful."

Many workers whose offices are near the APEC venues are walking for several kilometers to get to work because of the tight security.

Jaime Rocete, 63, says "workers are having a difficult time, especially for those who are sick, with arthritis, it's hard to walk."

China is unhappy with Japanese comments about territorial tensions in the South China Sea.

Japan has voiced objections to Chinese moves to expand its claims in the South China Sea that Tokyo says are violating international law and threatening free navigation and flight in the region. Japan has also sparred with Beijing over their conflicting claims to uninhabited islands in the East China Sea.

At a daily press briefing in Beijing on Tuesday, Chinese Foreign Ministry spokesman Hong Lei said China was "dissatisfied with the remarks and actions of the Japanese side." He accused Japan of trying to stoke tensions over an issue it is not directly involved with.

The territorial spats are not on the APEC agenda, though are drawing attention.
