Question: Adolfo Diaz negotiated with Germany and Japan to resurrect what planned shipping route through Nicaragua to connect the Caribbean Sea (and therefore the Atlantic Ocean) with the Pacific Ocean?

Context paragraphs:
Nicaragua Canal: The Nicaraguan Canal (Spanish: "Canal de Nicaragua" ), formally the Nicaraguan Canal and Development Project (also referred to as the Nicaragua Grand Canal, or the Grand Interoceanic Canal) is a planned shipping route through Nicaragua to connect the Caribbean Sea (and therefore the Atlantic Ocean) with the Pacific Ocean.  Its viability has been questioned by shipping experts and engineers.  "Major works" such as dredging will take place after the finishing of a Pacific Ocean wharf, whose construction was planned to start in late 2016.

Mona Passage: The Mona Passage is a strait that separates the islands of Hispaniola and Puerto Rico.  The Mona Passage connects the Atlantic Ocean to the Caribbean Sea, and is an important shipping route between the Atlantic and the Panama Canal.

Parting of the Waters: Parting of the Waters is an unusual hydrologic site at Two Ocean Pass on the Great Divide, within the Teton Wilderness area of Wyoming's Bridger-Teton National Forest.  Two Ocean Pass separates the headwaters of Pacific Creek, which flows west to the Pacific Ocean, and Atlantic Creek, which flows east to the Atlantic Ocean.  At Parting of the Waters, at , North Two Ocean Creek flows down from its drainage on the side of Two Ocean Plateau and divides its waters more-or-less equally between its two distributaries, Pacific Creek and Atlantic Creek.  From this split, Two Ocean Creek waters flow either 3488 mi to the Atlantic Ocean via Atlantic Creek and the Yellowstone, Missouri and Mississippi Rivers, or 1353 mi to the Pacific Ocean via Pacific Creek and the Snake and Columbia Rivers.  In the marshy area of Two Ocean Pass adjacent to Parting of the Waters, water actually covers the Continental Divide such that a fish could swim from the Pacific Ocean to the Atlantic Ocean drainages.  In fact, it is thought that this was the pass that provided the route for Yellowstone cutthroat trout to migrate from the Snake River (Pacific) to Yellowstone River (Atlantic) drainages.

Hurricane Otto: Hurricane Otto was the first tropical cyclone since Hurricane Cesar–Douglas in 1996 to survive the crossover from the Atlantic Ocean to the Pacific Ocean.  Forming late on November 20 in the southwestern Caribbean Sea, Otto was the fifteenth and final named storm, seventh hurricane and fourth major hurricane of the 2016 Atlantic hurricane season.  It quickly intensified into a strong tropical storm the next day, and on November 23–24, rapidly strengthened into a Category 3 major hurricane, the first in the month of November since Hurricane Paloma in 2008, and the latest date an Atlantic hurricane attained such intensity on record.  Otto made landfall in Nicaragua at peak intensity on November 24, thus becoming the latest hurricane to make landfall in the Atlantic basin since 1851 when records began.  Traveling along the Nicaragua–Costa Rica border, the system rapidly weakened to a tropical storm before emerging over the eastern Pacific Ocean, becoming the final storm of the 2016 Pacific hurricane season as well.  Hostile environmental conditions inhibited reorganization, and Otto subsequently degenerated into an elongated trough on November 26.

Adolfo Díaz: Adolfo Díaz Recinos (15 July 1875 Alajuela, Costa Rica – 29 January 1964, San José, Costa Rica) was the 12th President of Nicaragua between 9 May 1911 and 1 January 1917 and 18th between 14 November 1926 and 1 January 1929.  Born in Costa Rica to Nicaraguan parents in 1875, he worked as a secretary for the La Luz y Los Angeles Mining Company, an American company chartered in Delaware that owned the large gold mines around Siuna in eastern Nicaragua.  In this capacity, he helped channel funds to the revolt against Liberal President José Santos Zelaya, who had incurred the anger of the United States by negotiating with Germany and Japan to resurrect the proposed Nicaragua Canal.  Díaz became Vice President of Nicaragua in 1910.  After he became president in 1911, Díaz was forced to rely on U.S. Marines to put down a Liberal revolt, which resulted in a contingent of Marines remaining in Nicaragua for over a decade.  In return, in 1914, he signed the Bryan-Chamorro Treaty, which granted the United States exclusive rights to build an inter-oceanic canal across Nicaragua.

Transpolar Sea Route: The Transpolar Sea Route (TSR) is a future Arctic shipping route running from the Atlantic Ocean to the Pacific Ocean across the center of the Arctic Ocean.

Jamaica Channel: The Jamaica Channel is a strait separating the islands of Jamaica and Hispaniola, in the Caribbean Sea.  Along with the Windward Passage to its north, it connects the Caribbean Sea to the North Atlantic Ocean.  Due to its location about 1000 km north-east of the Panama Canal, it is a main sea lane through which vessels with Pacific Ocean destinations sailing from the eastern seaboards of the United States and Canada, as well from Europe, frequently pass.

History of Nicaragua: Nicaragua is the third least densely populated nation in Central America, with a demographic similar in size to its smaller neighbors.  It is located about midway between Mexico and Colombia, bordered by Honduras to the north and Costa Rica to the south.  Nicaragua ranges from the Caribbean Sea on the nation's east coast, and the Pacific Ocean bordering the west.  Nicaragua also possesses a series of islands and cays located in the Caribbean Sea.

History of the Nicaragua Canal: There is a long history of attempts to build a canal across Nicaragua to connect the Atlantic Ocean with the Pacific Ocean.  Construction of such a shipping route—using the San Juan River as an access route to Lake Nicaragua—was first proposed in the early colonial era.  Napoleon III wrote an article about its feasibility in the middle of the 19th century.  The United States abandoned plans to construct a waterway in Nicaragua in the early 20th century after it purchased the French interests in the Panama Canal.  The Panama Canal was built and that is now the main connecting route across Central America.

Puerto Rico Highway 901: Puerto Rico Highway 901 is a temporary primary highway in the southeast of Puerto Rico, beginning in PR-3 in Yabucoa, Puerto Rico and ending in PR-760 in Maunabo, Puerto Rico.  PR-3, in Yabucoa, enters downtown and continues uphill into the mountains.  Therefore, the Department of Transportation designed PR-901 as a primary route (this having the blue-white designation in the boards) while PR-53 is being constructed, because it is more direct to the area of Maunabo than PR-3, as the latter has more curves.  It goes parallel to the coastline for several kilometers, but due to the mountains ending up in the very shore, PR-901 is a high road (thus, a dangerous road) and the Caribbean Sea is about several hundreds of feet below the road's level, making PR-901 a scenic route which also gives it the distinction of being one of the few roads in the island to offer a very beautiful view of the Caribbean Sea (Or Atlantic Ocean) since this is the highest coastline in all of Puerto Rico (Cordillera Central ends exactly at the Vieques Passage).  Some views, especially before approaching the new tunnels of PR-53 of the road are very similar to the views of the Pacific Ocean from California Route 1 in California.  Yet, people have to be extremely cautious in this road.  People who go from Humacao to the area of Guayama are recommended to take PR-30, PR-52 and then PR-53 (Salinas-Guayama) than the PR-3/PR-901 route, because it is more safe and takes the same time.  This will end when PR-53 is finished.
