What about SriLankan own govt. support to LTTE ??
Premadasa government support
The Indian intervention was also unpopular among the Sinhalese majority. Prime Minister
Ranasinghe Premadasa pledged to withdraw IPKF as soon as he is elected president during his presidential election campaign in 1988. After being elected, in April 1989, he started negotiations with LTTE. President Premadasa ordered the
Sri Lanka Army to clandestine handed over arms consignments to the LTTE to fight the IPKF and its proxy, the Tamil National Army (TNA). These consignments include RPG guns, mortars, self-loading rifles, T81 automatic rifles,
T56 automatic rifles, pistols, hand grenades, ammunition, and communications sets.
[63] Moreover, millions of dollars was also passed on to the LTTE.

Presidency
Premadasa met with less success in dealing with Sri Lanka's
civil war. When he assumed office, he faced a rebellion in the south from the hardline Sinhala-nationalist, Marxist
Janatha Vimukthi Peramuna (JVP). The security forces brutally put down the revolt and killed many of its leaders. In the north, the
Liberation Tigers of Tamil Eelam were facing off against the
Indian Peace-Keeping Force. The Indian presence on the island was unpopular, and Premadasa requested India to leave. In order to force IPKF to leave the island, he authorized a clandestine operation to supply arms to LTTE according to the report published by the Sri Lankan Presidential commission to inquire into the 1992 assassination of one of the senior most officers in the Sri Lankan army, Lt Gen
Denzil Kobbekaduwa.
[4] The inquiry also found that Premadasa ordered clandestine supply of arms to LTTE. In the end, LTTE massacred 774 policemen using the same weapons he had given to LTTE (the policemen were asked to surrender to LTTE in Batticaloa at Premadasa's request).
[5][6] After the IPKF left in 1990, the government's war with the LTTE resumed, and resulted in stalemate.
