Primarily centred along the road connecting Myitkyina to Bhamo, Operation 0307 was launched to capture junta bases which could threaten Laiza, the headquarters of the KIA.

They seized a base overlooking the road between Hpakant and Kamaing, where checkpoints were used to extort civilians and collect vehicle fines.

[12] After the Chinese-brokered ceasefire in Northern Shan State between the Three Brotherhood Alliance and the Tatmadaw, the Kachin Independence Army (KIA), alongside the Kachin People's Defense Force (KPDF) and the All Burma Students' Democratic Front (ABSDF), began an offensive into northern Shan State with the objective to capture Mongmit District.

[14] During the offensive on Mongmit, the KIA and allied forces also began launching attacks on neighboring Mabein on 19 January.

[17] The KIA and the Ta'ang National Liberation Army (TNLA), members of the Northern Alliance and allies, began to experience tense relations in the beginning of February.

The soldiers told a TNLA checkpoint that they would not stay the night, but they proceeded to deploy in the town centre to celebrate Kachin Revolution Day, setting up flags and telling households to send representatives to a military parade they were reportedly holding the next day without informing the TNLA.

[18] Due to rumours that the KIA was planning to advance on the town from positions in Nam Hpat Kar, residents of Kutkai were concerned that clashes between the 2 armies could erupt.

[20] The KIA and AA continued defending their headquarters and they allege that junta airstrikes had landed on the Chinese side of the border, east of Laiza.

[1] The Irrawaddy predicted on 23 March that the KIA might attack Bhamo, the headquarters of the 21st Military Operations Command, as the next target of their offensive.

[24] On 28 March, KIA seized two junta bases in Yaw Yone and Nga Gayan near Lweje town on the Chinese border in Momauk Township.

[28] On 24 April, after weeks of attacks, the KIA captured Sezin, cutting off all major roads to Hpakant and completely encircling the town.

[32] The same day, the KIA announced that it had captured over 80 junta outposts, including 11 battalion headquarters, since the start of the offensive.

The next day, the entire road had been captured, with junta forces retreating from Sadung and Waingmaw, and cutting off Myitkyina from the border.

[46] Shortly after, junta forces launched a counteroffensive to retake the town, but were stalled at Aung Myay village.

[54] On 10 November, KIA forces captured Lanse village, the last NDA-K base in northern Kachin Special Region 1 (KSR1).
