As a result, in September 1999, the same month Australia entered East Timor, Indonesia officially abrogated 1995 agreement. Relations between the two nations stayed muted during the early 2000s, with Indonesia either delaying or flat-out cancelling most official engagements between the two nations. However, two occasions allowed for the restoration of strong political ties between Australia and Indonesia prior to the signing of the Lombok Treaty in 2006 - the Bali Bombings in 2002, and the Sixth Indonesia-Australia Ministerial Forum in 2003. Some anti-Australian sentiment remained in Indonesia, inflamed in early 2006 by Australia's welcoming of Papua New Guinean refugees in the midst of the Papua conflict with Indonesia. However, a new security treaty was proposed this time by Indonesian President Susilo Bambang Yudhoyono shortly before his Australia visit in April 2005, a proposal that would eventually become the Lombok Treaty.
