In Holland, a court is deciding whether to proceed with the trial of five suspected pirates caught allegedly trying to attack a Dutch-flagged freighter in January.
One of the accused's lawyers said he was a modern-day "Robin Hood" who attacks "ships of rich countries to give the ransom to poor families".
In Kuala Lumpur, Mr Mohamoud told the conference : "We need an effective coastguard to protect our fishermen from illegal fishing, to prevent dumping of toxic materials in our waters and fight shipping piracy.
"We ask the international community... to supply us with equipment and training."
Abdullahi Said Samatar, security minister in the pirate-ridden Puntland region of Somalia, told the BBC at the Malaysian meeting his government would not let foreign forces target land bases used by the pirates, saying that would be like "an invasion".
"No, you are not welcome to attack our area. But we will make a collaboration," he said. "We have to develop a collaboration on the ground."
The UN has authorised foreign military to use force against land bases, but this has yet to happen.
Somalia's anarchy has led to widespread poverty
The Malaysia conference is also expected to discuss what to do with pirates who are caught, as different countries have different policies.
Some alleged pirates have been put on trial in France and Kenya, while another has been flown to the US.
Some suspects have, however, been set free, with some arguing that international law is unclear on the matter.
A number of foreign navies have been patrolling the Indian Ocean and Gulf of Aden to deter pirates but the number of attacks has continued to rise.
As of 15 May, pirates have hijacked 29 ships and taken 472 crew hostage this year, according to the International Maritime Bureau watchdog.
International donors at a recent UN-sponsored conference pledged more than $250m (£165m) in military and development aid to Somalia.
UN bodies will oversee funding earmarked for the government, which wants to build a police force of 10,000 and a separate security force of 6,000.
Somalia has been without a stable government since 1991 and the chaos has allowed piracy to flourish.
