ROUGH CUT (NO REPORTER NARRATION)
STORY: China's President Hu Jintao arrived in Phnom Penh Friday on a four-day visit as the 20th ASEAN Summit was due to begin in Cambodia.
Cambodia beefed up security on Thursday ahead of Hu's visit to the summit which will be held from April 3 to 4.
China's influence in Cambodia is visible throughout the capital which is dotted by Chinese-funded projects.
The timing of Hu's visit has raised suspicion Beijing may pressure Cambodia to curb discussions at a Southeast Asian leaders' summit on the vexed question of the South China Sea. Phnom Penh has already said the issue is off the agenda.
Cambodia's authoritarian president Hun Sen says China's investments come with no strings attached, but the assertion will be tested when Hu makes his first visit on Friday.
