Question: Senjūrō Hayashi was a commander for the Chosen Army of Japan during the event that was a pretext for the invasion of what part of China?

<P0-S0> Fedor von Bock (3 December 1880 – 4 May 1945) was a German field marshal who served in the German army during the Second World War. <P0-S1>  Bock served as the commander of Army Group North during the Invasion of Poland in 1939, commander of Army Group B during the Invasion of France in 1940, and later as the commander of Army Group Center during the attack on the Soviet Union in 1941; his final command was that of Army Group South in 1942. <SEP> <P1-S0>  During the succession disputes in the Kingdom of Lan Na between King Setthatirath and King Mekuti, Sen Soulintha served Setthatirath as a general and successfully took several cities of Lan Na including Chiang Saen for which he was given the honorific name "Lusai" meaning “victory.” <P1-S1>  According to Lao histories Sen Soulintha was then installed as king a second time in 1580. <P1-S2>  When Setthatirath died near Attapeu under suspicious circumstances in 1572, Sen Soulintha led the armies of Lan Xang back to Vientiane. <P1-S3>  He and his son Ong Lo (Nakhon Noi) were captured by Bayinnaung and exiled to Pegu. <P1-S4>  By that time Sen Soulintha was an old man and reigned only for two years before his son ascended the throne as Nakhon Noi and another succession dispute ensued. <P1-S5>  Sen Soulintha was not of noble birth, rising from royal page to King Setthatirath’s Chief Minister. <P1-S6>  According to the Luang Prabang chronicles it was this brother, who had led a rebellion in Luang Prabang and tried to seize the throne from Setthathirath on the death of their father Photisarath. <P1-S7>  Prince Tha Heua took the regnal name Voravongsa and reigned under Burmese suzerainty from 1575-1579. <P1-S8>  Sen Soulintha supported Setthatirath in leading the guerrilla campaigns during the Burmese invasions of King Bayinnaung. <P1-S9>  Sen Soulintha defeated the Burmese and Lan Na forces led by Binnya Dala, an event which led to the latter’s exile, only to face a more massive invasion led by Bayinnaug the following year. <P1-S10>  In 1579, Bayinnaung dispatched a sizable army to restore order. <P1-S11>  A succession dispute erupted, which nearly led to civil war and provided a pretext for another Burmese invasion ordered by Bayinnaung and led by the Chief Minister Binnya Dala. <P1-S12>  Sen Soulintha again attempted to resort to guerilla tactics, but lacked popular support from his seizure of the throne. <P1-S13> Sen Soulintha, Saen Surintha or Sen Sourintha (1511–1582) was born Chane Tian and became King of Lan Xang reigning 1571-1575 and again 1580-1582. <P1-S14>  Voravongsa was never popular, and drowned with his family while attempting to flee Vientiane in the face of popular uprising. <SEP> <P2-S0> Senjūrō Hayashi (林 銑十郎 , Hayashi Senjūrō , 23 February 1876 – 4 February 1943) was an Imperial Japanese Army commander of the Chosen Army of Japan in Korea during the Mukden Incident and the invasion of Manchuria, and a Japanese politician and the 33rd Prime Minister of Japan from 2 February 1937 to 4 June 1937. <SEP> <P3-S0> The Mukden Incident, or Manchurian Incident, was a staged event engineered by Japanese military personnel as a pretext for the Japanese invasion in 1931 of northeastern China, known as Manchuria.
