Cygnus X is one of the closest giant molecular cloud complexes and thereforean extensively studied region of ongoing high mass star formation. However, thedistance to this region has been a long-standing issue, since sources atgalactic longitude of ~80 degrees could be in the Local Arm nearby (1-2 kpc),in the Perseus Arm at ~5 kpc, or even in the outer arm (~10 kpc). We usecombined observations of the EVN plus two Japanese stations to measure veryaccurate parallaxes of methanol masers in five star-forming regions in Cygnus Xto understand if they belong to one large star-forming complex or if they areseparate entities located at different distances. Here we report ourpreliminary result for W75N based on six epochs of VLBI observations: we findthat W75N is at a distance of 1.32^{+0.11}_{-0.09} kpc, which is significantlycloser than the reported values in the literature (1.5-2 kpc).
