ROUGH CUT (NO REPORTER NARRATION)<br/> <br />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.<br/> <br />Cambodia beefed up security on Thursday ahead of Hu's visit to the summit which will be held from April 3 to 4.<br/> <br />China's influence in Cambodia is visible throughout the capital which is dotted by Chinese-funded projects.<br/> <br />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.<br/> <br />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.
