PHNOM PENH — Cambodia, one of the least developed parts of Southeast Asia, extends a welcoming hand to economic aid from Japan and China, but analysts in the country are wary of the competitive intent of the nation's two largest aid donors.

Officially, the government hails both countries as champions of Cambodia's rehabilitation and development via their economic aid programs.

Japan has provided about $130 million a year since the early 1990s, mostly in the form of grant aid, while China channels its assistance largely through loans.
